Before the Blight, becoming an adult was something teenagers looked forward to. But now, turning eighteen means certain death. Unless you prove yourself worthy of the Cure. On her seventeenth birthday, Ashen Spencer is blindfolded and escorted to the massive, mysterious building known as the Arc to begin her year of training and testing in hopes that she can earn the Cure—a powerful drug given only to those deemed worthy to survive beyond their eighteenth birthday. Ashen has a chance to rise up from her former life of squalor and be granted a place in society, if the Panel—the mysterious group of powerful men and women in charge of the Arc—deems her year a success. She’s assigned to work for twelve months as a servant for a wealthy family whose son is the most alluring young man she’s ever met. At first, Ashen is grateful for the opportunity to earn her place in a society she’s always dreamed of inhabiting. But as time passes and she begins to learn the truth about the people she admires so much and the home she left behind, she realizes she has a choice: Be part of the disease… Or be part of the Cure.

Training continues, and Ash has just begun to scratch the surface of the secrets behind the Blight—the disease that's been killing off the entire adult population—and about the Aristocracy, the powerful and wealthy residents of the Arc who control everything. With allies on both sides of the battle, which side will Ash ultimately choose? In need of help, she turns to an unlikely ally—as well as old friends—in the beginnings of an Uprising of unprecedented proportions. Will she and the others succeed, or will her people be swept up in a war that they can never win?

The Uprising is gaining ground. But supplies are scarce, and the Aristocracy is more powerful than anyone ever imagined. Ash's fight may be unwinnable...but the affection of a certain young man may just give her the strength she needs to persevere.

When Ashen heads east to New York City to find Finn's brother, she finds herself confronted by an entirely new set of problems. The city is a war zone overshadowed by the Behemoth, the largest Arcology in existence. Few are allowed entry, and those who go in never leave. At first, Ashen assumes the power structure is one she knows well: Directorate vs. Dregs, Wealthy vs. Poor. She's seen this fight before, and she knows how to win it. She soon discovers that the power in New York is held entirely by one young man. Known only as the Bishop, he's mysterious, unnervingly handsome, and smooth-voiced. His allure is undeniable, despite his tendency toward cruelty. But as Ashen gets to know him, she begins to question how he managed to gain so much power at such a young age. Who is the Bishop, really? And where did he come from? The even more mysterious question is.... What exactly goes on inside the Behemoth?

After barely escaping with her life, Ashen finds her way home to the Arc, thanks to the help of an old friend. After a long absence, Ash isn’t sure what she’s about to find. The Bishop’s deception and cruelty have turned her world upside down, leaving her reeling as a wedge is driven between her and Finn, forcing them to live separate lives. Worse still, when she arrives, she is faced with the challenge of proving to the Arc’s leaders that she’s telling the truth about all that has happened since she left home. As she fights an impossible uphill battle, she must confront betrayal, lies, and heartbreaking loss that will either lead to her vindication or her ultimate downfall. With enemies vanquished, alliances solidified, and old friendships renewed, the end seems near for Ash in her final battle against tyranny… Or is it? Reign is the fifth and final book in The Cure Chronicles Series.
