“
The raft finally got here,” he said. Calypso snorted. Her eyes might have been red, but it was hard to tell in the moonlight. “You just noticed?” “But if it only shows up for guys you like—” “Don’t push your luck, Leo Valdez,” she said. “I still hate you.” “Okay.” “And you are not coming back here,” she insisted. “So don’t give me any empty promises.” “How about a full promise?” he said. “Because I’m definitely—” She grabbed his face and pulled him into a kiss, which effectively shut him up. For all his joking and flirting, Leo had never kissed a girl before. Well, sisterly pecks on the cheek from Piper, but that didn’t count. This was a real, full-contact kiss. If Leo had had gears and wires in his brain, they would’ve short-circuited. Calypso pushed him away. “That didn’t happen.” “Okay.” His voice sounded an octave higher than usual. “Get out of here.” “Okay.” She turned, wiping her eyes furiously, and stormed up the beach, the breeze tousling her hair. Leo wanted to call to her, but the sail caught the full force of the wind, and the raft cleared the beach. He struggled to align the guidance console. By the time Leo looked back, the island of Ogygia was a dark line in the distance, their campfire pulsing like a tiny orange heart. His lips still tingled from the kiss. That didn’t happen, he told himself. I can’t be in love with an immortal girl. She definitely can’t be in love with me. Not possible. As his raft skimmed over the water, taking him back to the mortal world, he understood a line from the Prophecy better—an oath to keep with a final breath. He understood how dangerous oaths could be. But Leo didn’t care. “I’m coming back for you, Calypso,” he said to the night wind. “I swear it on the River Styx.
