I don't usually read sci-fi books, so I didn't know what to expect from this book and if I would like it. I am so glad I gave it a chance! This was such a well written, unique story with twists and turns that I didn't see coming. In many books you can guess the twist/secret quite early in the book but with Archetype I really did not guess what happened to Emma and why she didn't remember who she was. I was shocked and surprised when her secret was revealed. When I finished the book I couldn't stop thinking about Emma, Declan and Noah and wanted to know badly how their story would end. I can't wait to read the sequel Prototype.
