TESSA IS A VARIANT, able to absorb the DNA of anyone she touches and mimic their appearance. Shunned by her family, she’s spent the last two years training with the Forces with Extraordinary Abilities, a secret branch of the FBI.

When a serial killer rocks a small town in Oregon, Tessa is given a mission: she must impersonate Madison, a local teen, to find the killer before he strikes again.

Tessa hates everything about being an impostor - the stress, the danger, the deceit - but loves playing the role of a normal girl. Disguised as Madison, she finds friends, romance, and the kind of loving family she’d do anything to keep.

Amid action, suspense, and a ticking clock, this super-human arrives at a very human conclusion: even a girl who can look like anyone struggles the most with being herself.
