Until a twist of fate forces her to kill one of her own. To punish her daughter, the Sea Queen transforms Lira into the one thing they loathe most—a human. Robbed of her song, Lira has until the winter solstice to deliver Prince Elian’s heart to the Sea Queen or remain a human forever. The ocean is the only place Prince Elian calls home, even though he is heir to the most powerful kingdom in the world. Hunting sirens is more than an unsavory hobby—it’s his calling. When he rescues a drowning woman in the ocean, she’s more than what she appears. She promises to help him find the key to destroying all of sirenkind for good—But can he trust her? And just how many deals will Elian have to barter to eliminate mankind’s greatest enemy?

Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish. Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company. His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species. And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone. Or does he?

Against the unforgiving landscape of a hospital, I fell in love with a mischievous, sun-eyed boy who became my only joy in that desolate place. That’s what made it all the more soul-crushing when he committed suicide in front of me. Since then, I've sworn never to love anyone again. With three exceptions: My friends, Sony, Neo, and Coeur, a little gang of rebellious, dying kids. Sony leads the charge with the air of freedom and only one lung to breathe it. Neo, a bad-tempered and wheel-chaired writer, keeps track of our great deeds from stealing to terrorizing our nurse. Coeur is the beautiful boy, the muscle, the gentle giant with a failing heart. Before death inevitably knocks down our doors, my thieves and I have one last heist planned. A great escape that will take us far from abusive parents, crippling loss, and the realities of our diseases. So what happens when someone else walks through the door? What happens when a girl joins our party and renders me speechless with her mischievous smile? What happens when she has suns in her eyes, and as terrified as I am to lose again, I start to fall?
