Read Chapter 1: The Dive That Went Wrong

The water was a knife-cut of cold blue, and Mack Donovan’s lungs were starting to burn.

He hovered at ninety feet, finning slow over the reef’s bone-white shelf, his dive light casting a pale cone through the haze of silt his anchor had kicked up. The wreck below him—a half-buried Spanish galleon, or what was left of her—was supposed to be the payday. The client had paid for three days of survey, and Mack had promised him bronze cannons and silver bullion. What he’d found instead was a ribcage of timber, a shattered mast, and about eight thousand dollars’ worth of iron fittings that would barely cover the cost of the diesel to get here.

He checked his pressure gauge. Fifteen minutes. He blew a frustrated stream of bubbles and signaled to Rosa, who hung ten feet above him like a patient shark, her camera rig ready but her shoulders already telling him she knew the score. She gave him a thumbs-down, and Mack nodded. Another bust. Another empty promise from a sea that had stopped paying out years ago.

He kicked upward, feeling the familiar weight of disappointment settle into his chest like a second lung. The sun was a silver coin far above, and the surface was a mirror of shattered light. He broke through it, ripped his regulator out, and spat salt water.

“Anything?” Pete called from the deck of the *Sea Serpent*, leaning over the rail with a cup of coffee in one hand and a cigarette in the other.

“Yeah,” Mack said, treading water. “A lot of nothing.”

But then the client’s yacht screamed.

It was a sound Mack had never heard a boat make—a high, metallic shriek of twisting steel, followed by the crack of something enormous breaking. The yacht, the *Meridian*, was a hundred and twenty feet of pristine white fiberglass and chrome, anchored two hundred yards away, and its stern was suddenly tilted hard to port, the water around it churning red and white.

“What the hell—” Pete dropped his coffee.

A great white shark, twenty feet if it was an inch, exploded out of the water mid-breach, its body a torpedo of muscle and rage. It came down on the yacht’s swim platform with a crunch that Mack felt through the water, then thrashed, its tail whipping the sea into a foam. On deck, three deckhands were shouting, hauling at ropes, and a woman in a white bikini was screaming, pointing at something Mack couldn’t see.

Rosa surfaced beside him, mask off and eyes wide. “Did it bite the prop?”

“It bit the *boat*,” Mack said.

The shark dropped back into the water, and for a moment, there was a horrible stillness. Then the *Meridian*’s engines roared to life, and the yacht started to move, dragging its anchor chain with a terrible clatter. The shark was gone—vanished into the deep blue like a bad dream—but the damage was done. The yacht’s stern was a mess of torn fiberglass and exposed hydraulic lines, listing noticeably as it powered away from the reef.

Mack swam to the ladder and hauled himself aboard, water sluicing off his wetsuit. Pete was already at the helm, winding the winch to pull the anchor.

“Abort,” Mack said. “We’re done here.”

“But our equipment—” Rosa started.

“It’s still on the bottom. We’ll come back for it. The client’s gone, and I’m not staying in the same water as that thing.”

Rosa didn’t argue. She stripped off her tank and started coiling lines while Pete throttled the engine, and the *Sea Serpent*, a forty-two-foot salvage boat with rust patches and a tired heart, chugged away from the reef. Mack watched the *Meridian* shrink on the horizon, watched the last of his hoped-for payout disappear with it.

By the time they docked in Nassau, the sun was a bruised orange over the harbor, and Mack’s bank account was a corpse.

He was in the wheelhouse, towel around his neck, doing the math in his head. Thirty days. He had thirty days before Eduardo Reyes’s goons came for the *Sea Serpent*, and that was if he sold the spare engine block and his dive compressor. He’d been a Navy diver, decorated, the kind of man who could hold his breath under ice and not flinch. Now he was two missed payments away from watching everything he owned get shrink-wrapped and auctioned to some tourist with a hard-on for maritime memorabilia.

Pete ducked his head in. “Guy on the dock asking for you.”

“Who?”

“The kind of guy who doesn’t ask.”

Mack sighed and stepped out onto the deck. Eduardo Reyes stood on the weathered planks of the dock, flanked by two men in linen suits who looked like they’d been poured out of a concrete mold. Reyes himself was smaller than his goons, immaculate in a cream-colored jacket, his hair oiled back, his smile all teeth and no warmth. He held a leather briefcase and wore the expression of a man who owned everything in sight.

“Mack,” Reyes said, arms wide. “You look well. The sea agrees with you.”

“Eduardo,” Mack said, not moving from the deck. “You’re a long way from Miami.”

“I’m everywhere, Mack. That’s the business.” Reyes stepped onto the *Sea Serpent*’s deck without being invited, his loafers silent on the fiberglass. “I heard about your little shark problem. Unfortunate. Very cinematic, though. You might get a documentary out of it.”

“What do you want?”

Reyes’s smile didn’t waver. He opened the briefcase and pulled out a sheaf of papers—Mack recognized the loan documents, the ones with the red stamps and the notary signatures. “Your balance, with interest, is due in thirty days. That’s not my choice, Mack. I have partners. They don’t have your charming personality to fall back on.”

“I know what I owe.”

“Do you? Because my records show you’ve made exactly zero payments in the last four months.” Reyes tapped the papers. “I’m not a monster. I’m giving you a month. But when that month is up, I take the boat, the permit, and that little spark plug of an engine you’ve got in the hold. You’ll be swimming to work.”

Mack’s jaw tightened. He wanted to throw the man off his boat, wanted to watch him splash into the green water of the harbor, but he’d done that dance before, and it always ended with a broken rib or a missing contract. “You’ll get your money.”

“Thirty days, Mack.” Reyes turned and walked back to the dock, his goons falling into step behind him. “Don’t make me come back.”

They drove off in a black SUV, leaving Mack standing on the deck of his boat, the sunset casting long shadows across the water. Rosa came out of the cabin, arms crossed, eyes hard.

“We’re screwed,” she said.

“Not yet.” Mack turned and walked into the wheelhouse, pulled his phone from his pocket. There was a message waiting for him—a text from a number he didn’t recognize, no preamble, no signature. Just a single line of text, glowing on the cracked screen.

*Find the Catalina.*

He stared at it. The Catalina. The name was familiar, a half-remembered story from his Navy days, a legend passed around in bars and dive shops. The *Santa Catalina*, Silas Blackwood’s ship. He’d heard the tale a hundred times—Blackwood’s betrayal, his dying curse, the claim that his ship would sail again with its treasure intact, waiting for someone foolish enough to claim it.

He’d always thought it was a ghost story. But the message sat there, waiting, a thread pulling at something in his chest.

Pete leaned in. “What is it?”

“I don’t know yet.” Mack pocketed the phone. “But I’m going to find out.”

He stared at the harbor, at the lights flickering on across the water, and felt the first stirring of something he hadn’t felt in months. Not hope. Not yet. But something close. A path, maybe. A way out.

The dive had gone wrong. The money was gone. But somewhere out there, at the bottom of the sea, a dead captain was waiting, and Mack Donovan was the kind of fool who would go looking for him.
