Disease wipes out world's humans. Family hides in underground. Boy narrator grows up, falls in love with another boy.

New York City has been decimated by war and plague, and most of civilization has migrated to underground enclaves, where life expectancy is no more than the early 20's. When Deuce turns 15, she takes on her role as a Huntress, and is paired with Fade, a teenage Hunter who lived Topside as a young boy. When she and Fade discover that the neighboring enclave has been decimated by the tunnel monsters—or Freaks—who seem to be growing more organized, the elders refuse to listen to warnings. And when Deuce and Fade are exiled from the enclave, the girl born in darkness must survive in daylight—guided by Fade's long-ago memories—in the ruins of a city whose population has dwindled to a few dangerous gangs. Ann Aguirre's thrilling young adult novel is the story of two young people in an apocalyptic world—facing dangers, and feelings, unlike any they've ever known.

When rebellion destroys the underground world in which Thimble and Stone have grown up, they take Stone's son and try to escape the chaos. Along the way, they must evade the Freaks, beings who feed on human flesh. Leaving behind the roles of Builder and Breeder which they were assigned at birth, they wander the underground tunnels, looking for safety yet afraid to go "topside" where legend has it that the light and water will burn their skin from their bones. Their journey takes them upward to an unimagined world of tinned food, comfortable furniture, and books. Away from their regimented society for the first time, and still facing imminent danger, Thimble and Stone acknowledge the forbidden attraction which both have denied for years.

Deuce’s whole world has changed. Down below, she was considered an adult. Now, topside in a town called Salvation, she’s a brat in need of training in the eyes of the townsfolk. She doesn't fit in with the other girls: Deuce only knows how to fight. To make matters worse, her Hunter partner, Fade, keeps Deuce at a distance. Her feelings for Fade haven’t changed, but he seems not to want her around anymore. Confused and lonely, she starts looking for a way out. Deuce signs up to serve in the summer patrols—those who make sure the planters can work the fields without danger. It should be routine, but things have been changing on the surface, just as they did below ground. The Freaks have grown smarter. They’re watching. Waiting. Planning. The monsters don’t intend to let Salvation survive, and it may take a girl like Deuce to turn back the tide.

If you wondered why Fade retreated from Deuce at the end of Outpost, find out in his own words.

Listening Length: 14 hours and 3 minutes The epic conclusion to Ann Aguirre's USA Today best-selling trilogy. The horde is coming. Salvation is surrounded, monsters at the gates, and this time, they're not going away. When Deuce, Fade, Stalker and Tegan set out, the odds are against them. But the odds have been stacked against Deuce from the moment she was born. She might not be a Huntress anymore, but she doesn't run. With her knives in hand and her companions at her side, she will not falter, whether fighting for her life or Fade's love. Ahead, the battle of a lifetime awaits. Freaks are everywhere, attacking settlements, setting up scouts, perimeters, and patrols. There hasn't been a war like this in centuries, and humans have forgotten how to stand and fight. Unless Deuce can lead them. This time, however, more than the fate of a single enclave or outpost hangs in the balance. This time, Deuce carries the banner for the survival of all humanity.

The Razorland saga continues. Since the war ended, Tegan has dreamed of an epic journey, so when she has the opportunity to sign on as ship's doctor, she can't wait. It's past time to chart her course. Millie Faraday, the kindest girl in the free territories, also yearns to outrun her reputation, and warrior-poet James Morrow would follow Tegan to the ends of the earth. Their company seems set, but fate brings one more to their number. Tegan will battle incredible odds while aiding Szarok, the Uroch vanguard, who has ventured forth to save his people. Szarok is strange and beautiful, like a flower that blooms only in the dark. She shouldn't allow him close, as such a relationship is both alien and forbidden. But through stormy seas and strange lands, she will become stronger than she ever knew. Adventures almost never go according to plan, and when she understands what her heart truly wants, it might change her life forever.
