CORBAN

"Everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock."

Matthew 7:24

This book is about a secret castle that has stood strong under the sand for longer than anyone can remember. Jesus once told a story about why some houses stand and others fall. It all comes down to what you build on.

Now that there were three of them, the Tide Trio had a brand new problem, and it was not a monster. It was a much smaller, much more embarrassing problem.

They had nowhere to go.

Real superheroes have a base. A secret lair. A place to plan and train and keep their snacks. The Tide Trio had a tree in Corban's backyard and a cooler with three juice boxes in it. That was the entire operation.

They were about to find something a great deal better, hidden in the very last place anybody would look. Right out in the open, on the beach, where a thousand people walk past it every single day.

It was waiting for them. It had been waiting a very long time.

The Saturday after they became the Tide Trio, the three boys went back to the beach to celebrate. And there, near the dunes, sat a sandcastle.

Not a normal sandcastle. This one was big, almost as tall as Jackson, with crooked turrets and a single seashell glowing softly on the highest tower. And here is the strange part. It had not been there the day before. Nobody had built it. The tide had not washed it away in the night, which tides always do.

"Okay, that is definitely weird," said Corban.

Hudson, who noticed everything, pointed at the glowing shell. "It only lights up when we get close. Watch." He took three steps back, and the glow faded. He stepped forward, and it brightened. It was reacting to them.

Jackson, who never met a button he did not want to press, was already reaching for it.

"Jackson, wait, we don't know what that does," said Hudson.

"That is exactly why I'm pressing it," said Jackson, and he pressed the glowing shell.

The whole beach began to rumble.

The sand around the castle did not collapse. It opened. Like a flower, like a door, like something that had been built to do exactly this, it folded back and revealed a smooth round platform with a railing.

The platform was an elevator. The three boys stood very still as it carried them down through the cool dark sand, past layers of rock, past the roots of the dunes, deeper than any basement, deeper than any swimming pool, into a soft blue glow rising up to meet them.

"If we get grounded for this," Hudson whispered, "it is entirely Jackson's fault."

"Worth it," Jackson whispered back.

And then the elevator stopped, the doors slid open, and all three boys forgot how to speak.

It was enormous. A great glowing cavern carved into the rock beneath the dunes, with a curved glass wall on one side that looked straight out into the deep blue sea. Fish drifted past the glass like clouds.

There was a launch bay. A training room with floating targets. A round table shaped like a wave. A pool of glowing blue water in the very center that lit the whole place up. And a snack station, which Jackson found in under four seconds.

"Oh, sure," said a small bright voice. "Make yourselves at home. Eat the snacks. Three hundred years I keep this place ready, and the first thing the chosen heroes do is raid the pantry."

The boys spun around. Hovering in the air in front of them, no taller than a thumb, glowing teal and gold with little buzzing wings, was the crossest, tiniest, most wonderful creature any of them had ever seen.

"I'm Pip," she said, hands on her hips. "I run this place. And you three are LATE."

Pip was a Tide Fairy, and she was not alone. As the boys watched, dozens more little glowing fairies drifted up out of the blue pool, lighting the cavern like a sky full of slow stars. They were the ones who kept the Sandcastle alive. The glowing water, the humming gadgets, all of it ran on fairy light.

"This place was built long ago," Pip said, "for a team that could do what you three did out there. Three powers that braid into one. We have been waiting for the Tide Trio for a very, very long time. Took you long enough to find the doorbell."

Pip led them to the glowing pool in the center, the one she called the Glow Pool, and told them the biggest secret of all.

"Everybody knows the normal elements," she said. "Water. Fire. Earth. Air. Boring. Done a thousand times. But this sea is older and stranger than the world above remembers, and it holds elements that have no name in any book up there. We call them the Wild Elements."

She flicked her tiny hand at the pool, and the water lit up in colors the boys had never seen before. "Glimmer, light you can throw. Echo, sound you can hold in your hands. Stardust, that makes heavy things float. Gloop, sticky enough to trap anything. And a few others I'll show you when you're ready, which is not today, because today you are still tripping over your own feet."

Jackson reached toward the glowing water. "Can I try one?"

"Absolutely not," said Pip. And at that exact moment, far above their heads, an alarm began to scream.

Doctor Undertow, it turned out, did not like losing. And when a villain does not like losing, he tends to build something big and angry and made of metal.

He had gathered up every broken piece of his wrecked machines, all the rusted gears and bent pipes and busted bolts from two whole defeats, and he had welded them together into a giant. A clanking, stomping, twelve-foot iron monster with glowing red eyes and fists like wrecking balls. He called it the Rust Golem, and he sent it marching up onto the pier to smash everything Corban had ever protected.

The Tide Trio shot up the elevator and out onto the beach, suits glowing, ready to fight. And for a while, the fight went exactly the way you would expect three brave kids against a metal giant to go.

Badly.

Corban kicked the Rust Golem and nearly broke his foot. Jackson threw a boulder, and it bounced off with a CLANG. Hudson froze its legs, but the iron was so heavy it just shattered the ice and kept coming. Nothing worked. The giant was simply too big and too solid for three kids on dry land.

Pip zipped up beside Corban's ear, glowing bright. "You're fighting in the wrong place!" she shouted. "You're heroes of the TIDE. Stop standing on the sand like land creatures. Get in the water. The sea gives you more than you know!"

Corban did not understand. But he had learned, by now, to trust help when it was offered instead of trying to do everything alone. "Guys!" he called. "Into the waves! On three! And this time, trust her!"

The three of them turned and dove straight into the sea.

And the sea changed them.

Scales rippled up their arms. Their legs became powerful tails. Armor of coral and pearl locked into place, and a weapon appeared in each of their hands, a glowing spear for Corban, a frozen trident for Hudson, a stone hammer for Jackson. In the water, they were not three clumsy boys anymore. They were warriors.

Here is the thing about a giant made of iron. It is unstoppable on dry land. But iron has one great enemy in all the world, and that enemy is water.

The Tide Trio had a plan now, and for once they did it together. Hudson shot up out of the surf and splashed the Rust Golem head to toe, soaking every joint and gear. Jackson cracked the pier so the giant stumbled toward the deep end. And Corban, fast and bright in his warrior form, darted in close and taunted the great metal monster until it took one furious, stomping step too far.

The Rust Golem toppled off the end of the pier and crashed into the deep sea.

And there, in the cold salt water, the thing built from two defeats began to do what rust does. It seized. It groaned. It slowed, and slowed, and finally stopped, sinking quietly to the bottom in a cloud of orange flakes.

Far below, Doctor Undertow watched his giant fall apart, and screamed into a pillow made of kelp.

That night, back down in the Sandcastle, the Tide Trio sat around the wave-shaped table while the fairies glowed softly overhead. They were tired and salty and happy. For the first time, they had a home base. A real one.

"We could not have beaten that thing this morning," Corban admitted. "Not on the sand. Not by ourselves. We needed Pip. We needed the water. We needed each other."

"That," said Pip, landing on the table with a tiny thump, "is the smartest thing you have said all day."

Corban thought about his dad, and the garage, and the light in his chest. His dad had built him a suit, but he had never let Corban believe he had to do everything on his own. Asking for help was not the opposite of being strong. It was part of it. Maybe the biggest part.

He looked around the glowing cavern, at his two best friends and a sky full of fairies and a home that had been waiting for them all along, and he felt the way you feel when you finally walk into a place that was made for you.

"So," said Jackson, mouth full of snacks. "What's next?"

Pip's little face went serious. She drifted to the great glass wall and looked out into the deep, where the water turned from blue to black. "Next," she said quietly, "is bad. Something is wrong out on the reef. The colors are going out, one by one. And the creatures who live there are calling for help."

But that is a story for Book Four.

Super Corban is a made-up adventure. But the truth hidden inside this one comes from a real story Jesus told, in the Bible, in Matthew chapter 7.

Jesus described two builders. The wise one dug down deep and built his house on solid rock. The foolish one took the easy way and built his house on soft sand. From the outside, on a sunny day, both houses looked exactly the same.

Then the storm came. The rain poured, the rivers rose, and the wind beat hard against both houses. The house on the sand fell with a great crash. But the house on the rock did not even budge, because its foundation went down deep into something solid.

Jesus said the rock is Him, and listening to His words and actually doing them. The Sandcastle stands because it is built on something deep and strong. A whole life stands the very same way. Build it on Jesus, and no storm can knock it down.
