From Goodreads: Can Tessa pose as Madison . . . and stop a killer before it’s too late? 

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. 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 comes to a very human conclusion: even a girl who can look like anyone struggles the most with being herself.

If you’re a fan of X-Men, then this is definitely the book for you.  Tessa is a Variant; her special ability allowing her to morph her appearance into anyone after one simple touch.  And she’s about to go on her first mission: taking the place of a teenager on her death bed, another victim of what the FBI is certain is a serial killer Variant gone rogue.

But taking over someone’s life isn’t as easy as it sounds, even if you do look identical.  There’s the problem with memories, friendships, and daily interactions in general that Tessa is going to have to take in stride if she’s going to play her cards right and stop the killer before her time runs out—and that may be sooner than she thinks.  Forced to lie on a daily basis, torn between her feelings for her co-worker and the real Madison’s brother, Tessa has her work cut out for her as everything around her begins to unravel.

I thoroughly enjoyed this very fast-paced read!  I’ve always wished I had special abilities like the X-Men do, and Winnacker really brings it to life through her novel, Imposter.  There is a lot going on, and I must say, Winnacker did a great job putting me off the trail.  I had the wrong person pegged as the killer from the get-go, and while I sometimes questioned my choice, I stuck with them only to find that, in the end, Winnacker not only fooled Madison and her team, but me as well.  I really enjoy it when authors are able to keep me guessing, and that’s exactly what happened in this novel. Overall, it was a great read with just a few slow spots here and there, and I highly recommend it to any readers out there who love the idea of X-Men. Four stars.
