Unchanged (Unremembered Trilogy, 3) - Hardcover

So many secrets are buried within these compound walls.
I used to be one of those secrets.

After returning to the Diotech compound and undergoing an experimental new memory alteration, Seraphina is now a loyal, obedient servant to Dr. Alixter and the powerful company that created her. Happy and in love with Kaelen, another scientifically-enhanced human designed to be her perfect match, Sera's history with a boy named Zen is just a distant memory from a rebellious past she longs to forget.

But as Sera and Kaelen embark on a nationwide tour to promote Diotech's new product line--a collection of controversial genetic modifications available to the public--Sera's mind starts to rebel. She can't stop the memories of Zen from creeping back in.

As more secrets are revealed, more enemies are uncovered, and the reality of a Diotech-controlled world grows closer every day, Sera will have to choose where her true loyalties lie, but it's a choice that may cost her everything she's ever loved.
