Children of Eden by Joey Graceffa, Laura L. Sullivan

Rowan is a second child in a world where they are not allowed to exist.  She has to hide to remain safe.  She's homeschooled, runs a lot and is bored.  She loves her twin Ash.  He gets to go out into the world and she questions him endlessly about what he saw, who he talked to and what's happening outside their walls.  But you can't keep a person secret forever...

Atria/Keywords Press sent me a copy of this book to read for review (thank you).  It was published yesterday so you can get a copy now.

Everything that Rowan knows and thinks about her life is a lie.  When she attempts to escape, her mother helps her and tells her things that shatter her.  She was actually the first born.  Her father tried to kill her.  And the story of the world they have lived in for two hundred years is fantasy.

This is a tense suspenseful world where she has to try hard to stay alive.  She gets help from different people, she's not sure who to trust and she's torn between a girl and a boy.  She loves them both.  But she loves her brother more.

I was a bit disappointed with the ending.  There was no mention of this being part of a series, but the story isn't done yet.  She's started something and it's not finished yet...
