Rating: 4 out of 5.

This is a really good, creepy YA mystery/thriller that keeps your attention from page one. The book opens with Casey being mad that her sister Sutton is missing. She’s convinced that Sutton took off for selfish reasons and is laughing that everyone is frantically looking for her. Casey puts on a show as a worried sister for the cameras, but inside she’s fuming. There is no love lost between her and Sutton, but no way is she telling the police about their argument just before Sutton went missing.

When Sutton returns everyone is relieved. She claims to not remember anything and is acting strange, but Casey isn’t buying it. Especially when Sutton seems hyper focused on Casey and wants to spend time with her, something she never seemed to want to do before. Hoping to catch Sutton in a lie, Casey starts to dig into the days and weeks before Sutton went missing, and finds she may not have known her sister at all.

Told in alternate timelines of both Casey and Sutton, the author does a great job of building tension and suspense, with a few dashes of creepiness for good measure. Late into the night I found myself turning page after page to find out what would be revealed next. Anyone with a sibling that was close when younger, only to drift apart during puberty, will identify with the slights, hurts, and pangs of regret that litter almost everyone’s youth. The question is, will you figure out your mistake and mend fences before it’s too late?

If you like a quick, gripping page turner, definitely check this one out.

I was provided a complimentary e-copy of this book by NetGalley and SOURCEBOOKS, Fire. All opinions are my own.
