Get Nadia. Find a way out. Simple.”A week ago, seventeen-year-old Lela Santos’s best friend, Nadia, killed herself. Today, thanks to a farewell ritual gone awry, Lela is standing in paradise, looking upon a vast gated city in the distance—hell. No one willingly walks through the Suicide Gates, into a place smothered in darkness and infested with depraved creatures. But Lela isn’t just anyone—she’s determined to save her best friend’s soul, even if it means sacrificing her eternal afterlife. As Lela struggles to find Nadia, she’s captured by the Guards, enormous, not-quite-human creatures that patrol the dark city’s endless streets. Their all-too-human leader, Malachi, is unlike them in every way except one: his deadly efficiency. When he meets Lela, Malachi forms his own plan: get her out of the city, even if it means she must leave Nadia behind. Malachi knows something Lela doesn’t—the dark city isn’t the worst place Lela could end up, and he will stop at nothing to keep her from that fate.

    Dante Walker is flippin’ awesome, and he knows it. His good looks, killer charm, and stellar confidence have made him one of hell’s best—a soul collector. His job is simple: weed through humanity and label those round rears with a big red good or bad stamp. Old Saint Nick gets the good guys, and he gets the fun ones. Bag-and-tag. Sealing souls is nothing personal. Dante’s an equal-opportunity collector and doesn't want it any other way. But he’ll have to adjust, because Boss Man has given him a new assignment: Collect Charlie Cooper’s soul within ten days. Dante doesn't know why Boss Man wants Charlie, nor does he care. This assignment means only one thing to him, and that’s a permanent ticket out of hell. But after Dante meets the quirky Nerd Alert chick he’s come to collect, he realizes this assignment will test his abilities as a collector…and uncover emotions deeply buried.

    After the 2nd, only the lucky escape. And after the 3rd, only the unlucky survive. After the 4th wave, only one rule applies: trust no one.Now, it's the dawn of the 5th wave, and on a lonely stretch of highway, Cassie runs from Them. The beings who only look human, who roam the countryside killing anyone they see. Who have scattered Earth's last survivors. To stay alone is to stay alive, Cassie believes, until she meets Evan Walker. Beguiling and mysterious, Evan Walker may be Cassie's only hope for rescuing her brother-or even saving herself. But Cassie must choose: between trust and despair, between defiance and surrender, between life and death. To give up or to get up.
