Aria whimpered. Hanna looked like she was going to throw up. Emily’s heart thrummed jackrabbit-fast. Spencer’s jaw was set and hard as she steered toward the cove. In a minute, they had pulled so far away that they had a panoramic view of the entire ship. Tiny lifeboats peeled away from the hull. An alarm light blared on the top deck. Black smoke poured from the windows.
And then, Emily’s gaze returned to deck where the staff was organizing the remaining lifeboats. Naomi was still standing there, hands on hips, glaring. Emily watched her rigid figure until she got smaller and smaller, fainter and fainter, until she finally vanished into the growing darkness.

S.O.S.
It took about twenty minutes to get to the dive spot that Spencer’s group had been to that afternon. The sun had almost set; the last remaining light danced across the sky in purple streaks. Spencer turned the boat toward a section of coast that was marred by huge rock formations, natural cliffs, and small caves. Jagged coral jutted everywhere. Water lapped against slick, high, algae-covered rocks. The cave they were closest to was deep and black, looking like a scary, angry mouth.
Spencer cut the engine, then strapped on the oxygen tank and flippers, feeling a little uneasy about using the scuba equipment after almost drowning. But she’d checked the gauges three times, and there was no way Naomi could have fiddled with them before they left. “The deepest part is in that cave. I’ll go alone, okay? You guys stay here.”
“Are you crazy?” Emily said. “You can’t swim there alone. I’m going with you. I’ll tread water on the surface while you dive down.”
“So will I,” Hanna said.
Aria’s eyes widened. “Don’t leave me here! I’m coming, too.”
Spencer glanced at her worriedly. “Can you manage?”
Aria pulled a strap of her life vest. “I’ll be fine. We’re all in this together, right?”
“I’ll stay close to you,” Emily volunteered.
The girls tied the lifeboat to a natural outcropping of rocks and slipped into the cool, algae-filled water. They swam toward the narrow passage and into a dark, swirling pool. After a few more strokes, the passage opened into a wider cavern, where the water was much calmer and warmer. But it was pitch-black in there, too—Spencer could hardly see a few feet in front of her. It was barely better when she turned on the scuba flashlight she’d grabbed from the equipment room. The filmy, slimy seaweed kept slithering over her legs like leeches. She peeked worriedly at Aria, but she was bobbing comfortably in the life jacket.
She grabbed the necklace from Aria’s hand. “Wish me luck,” she declared, then disappeared under the water.
She sank down just like she had earlier that day. This time, her equipment worked, and oxygen filled her lungs. Once she was down far enough, she found an outcropping of rocks and pushed the necklace deep into the cove, dislodging a cloud of sand. When it cleared, the necklace was gone. It was hidden—hopefully for good.
When she popped back up, the girls were still treading water. There was a tense silence—Spencer could tell none of them had spoken the whole time she’d been down. Hanna’s teeth chattered. Aria was breathing heavily. Emily’s eyes darted back and forth toward the shore, which seemed a million miles away.
“It’s done,” Spencer said when she pulled the dive mask from her face. “Let’s go.”
They paddled back through the passage. The sea had grown even colder with the setting sun, and Spencer couldn’t wait to climb back on the lifeboat and head for land. She squinted at the tiny sliver of sun on the horizon. There was barely any distinction between the navy-blue water and the darkening sky. The only sound she heard was the peaceful lapping of waves. She looked right and left, disoriented. Something seemed different.
Emily surfaced behind her. Aria swam through next, then Hanna. They all treaded water with Spencer, looking around in confusion.
“Where’s the boat?” Emily finally said.
Spencer blinked. Just like that, her bearings came back to her. She saw the cruise ship far in the distance. And there was the finger-shaped rock she’d remembered from the dive earlier that day. But when she looked for the natural hook they’d tied the boat to, all she saw was a slack piece of rope. She pulled at it, feeling a weight rise up from the deep. An outboard motor appeared on the surface. After that, a limp shell of a raft, all of its air gone.
Aria gasped. Emily and Hanna exchanged a silent, horrified look. The waves lapped violently against the rocks. A thin, high-pitched giggle spiraled through the air.
Hanna let out a tiny squeak and stared at all of them with wide, terrified eyes. “I-I don’t understand.”
“Something must have punctured it,” Spencer suggested, her voice trembling.
Emily whimpered. “Is this actually happening? How are we going to get back to shore?”
