Ms. Winnacker is quickly becoming my favorite author. I went into this book expecting a typical YA story and instead I got something much deeper. It came with secrets, calculated plots with lots of twist and deaths.Plot: You know a plot is written well when your reading it and all of sudden you have to put the book down cause of the nerves that are racking up your system. The plot is done well you actually feel like you are in the story, experiencing every moment in Tessa shoes. Each chapter builds up nicely to another, leading up to an amazing ending.Love: Can this relationship be any more complicated? It’s not a love triangle with a guy. More like the guy can’t pick a girl. GAH! It really made my heart race and want to scream! It made me happy then sad. Nervous then excited. Basically, I felt like a teen and with that said, the author clearly got her point across well.Variants: I totally love this idea. To be able to mimic another persons DNA by just touching them. Imagine Mystic from X-men, but in teen form. And she is posing as s girl trying to stop the killer. All the while she is dealing with keeping her form, living with a family, and going to school. I think everything weaved well and left me totally excited for the next book.Cleverly packed with a stunning plot, Impostor is brilliant. Not predictable, but giving the reader exactly what they need… a fresh new story that leaves you on a threshold for more. A vibrant read that is unique and creative, Impostor rules.
