Book 1

The Rift Uprising

by Amy S. Foster

Published 4 October 2016

What’s the difference between the monsters you fight against and the monsters you fight for?

What do the multiverse and teenage super soldiers have in common?

Nothing.

And that’s Ryn Whittaker’s problem.

Ryn is a Citadel, specially chosen and trained to guard a Rift – one of fourteen unpredictable tears in the fabric of the universe that serve as doorways to alternate Earths – and she’s one of the Allied Rift Coalition’s best, until the day eighteen-year-old Ezra Massad comes tumbling out of The Rift and everything changes.

Despite her training, and the fact that any romantic entanglements are doomed by her violent, cybernetically-altered hormones, Ryn can’t keep away from Ezra, and what starts as a physical attraction quickly grows deeper. Ezra’s curiosity about The Rifts, the mysterious organization that oversees them, and the Citadels themselves echoes Ryn’s own growing doubts and unasked questions.

But can she fall in love, uncover the truth, and protect her friends and family? After all, she already knows that secrets have a price…and not keeping hers may cost Ryn more than she’s ready to lose.

Book 3

The Rift Coda

by Amy S. Foster

Published 9 October 2018

The exciting, action-packed finale to The Rift Uprising trilogy that rivals the thrills and action of The Hunger Games and Red Rising.

Ryn Whittaker started an uprising. Now she has to end it.

Not long ago, Ryn knew what her future would be – as a Citadel, it was her job to protect her version of Earth among an infinite number of other versions in the vast Multiverse at any cost. But when Ezra Massad arrived on Ryn’s Earth, her life changed in an instant, and he pushed her to start asking why she was turned into a Citadel in the first place.

What began as merely an investigation into her origins ended up hurling Ryn, Ezra, and Ryn’s teammate Levi through the Multiverse and headlong into a conspiracy so vast and complex that Ryn can no longer merely be a soldier… she must now be a general.

And in becoming a true leader, she must forge alliances with unpredictable species, make impossible decisions, and face deep sacrifices. She must lead not thousands, but hundreds of thousands of troops under her command and in doing so, leave any trace of her childhood behind.
