"High emotional stakes and an intriguing premise make this first entry in Foster's new trilogy a solid next read for those who enjoyed Pierce Brown's Red Rising or Veronica Roth's Divergent."" — Library Journal

An alternate reality that feels all-too-real, The Rift Uprising is the explosive start to a new trilogy that blurs the line between parallel universes—not to mention YA and adult science fiction—from acclaimed lyricist and storyteller Amy S. Foster.

Seventeen-year-old Ryn Whittaker is a Citadel: an elite, enhanced soldier specially chosen to guard a Rift, a mysterious and dangerous portal to alternate Earths scientists cannot control or close. Trained from the age of fourteen, Ryn can run faster, jump farther, and fight better than a Navy SEAL—which is good when you're not sure if a laser-wielding Neanderthal or an axe-wielding Viking is trying to make it through the Rift and into your world.

But the teenager's military conditioning and education have not prepared her for the boy who crosses through—a confused young man, seemingly lost and alone. While there's an immediate physical attraction, it's his intelligence and curiosity that throws Ryn off balance. The stranger asks disturbing questions about the Rift that Ryn herself has never considered—questions that lead her to wonder if everything about her life and what she's been told these past six years has been a lie. Are the Rifts as dangerous as her leaders say? Should her people really try to close them . . . or learn how to travel through them?
