Falls the Shadow by Stefanie Gaither

Goodreads blurb:

When Cate Benson was a kid, her sister, Violet, died. Two hours after the funeral, Cate’s family picked up Violet’s replacement. Like nothing had happened. Because Cate’s parents are among those who decided to give their children a sort of immortality—by cloning them at birth—which means this new Violet has the same smile. The same perfect face. Thanks to advancements in mind-uploading technology, she even has all of the same memories as the girl she replaced.

She also might have murdered the most popular girl in school.

At least, that’s what the paparazzi and the anti-cloning protesters want everyone to think: that clones are violent, unpredictable monsters. Cate is used to hearing all that. She’s used to defending her sister, too. But Violet has vanished, and when Cate sets out to find her, she ends up in the line of fire instead. Because Cate is getting dangerously close to secrets that will rock the foundation of everything she thought was true.

Falls the Shadow is an action filled clone book.  I think with the popularity of clones (Orphan Black, anyone?) this will move fairly well at my library.  It has a cool sister relationship that gives the story line a little much needed depth.  The romance was a little much for me, in that I didn’t feel like there was much chance for a real build.  It’s just “Oh yeah, he’s always been there, and says he always will be. So I guess I should believe him.”  I did like this one better than The Haven, because there was more science and world building, so I felt like I knew more about what was happening.
