Engineering For Teens

The first story in the fast-paced action-adventure The Rift Uprising trilogy - an enthralling mix of speculative fiction and military thriller - in which a young soldier comes to question the monsters she's trained to fight against...and the monsters she fights for. 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.

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.
