Lives are in the balance in bestselling author Caroline B. Cooney’s newest young adult thriller, Three Black Swans.

Missy and her cousin Claire are best friends who finish each other’s sentences and practically read each other’s minds. It’s an eerie connection—so eerie that Missy has questions she wants to put to her parents. But she’s afraid to ask. So when Missy hears an expert discussing newborn babies on the radio, it makes her wonder about her family.

Missy just can’t let go of those nagging questions, and decides to use a school project about scientific hoaxes to try to uncover the answers. She enlists Claire to help. As part of the project the girls perform a dramatic scene that is captured on video at school. After the video is posted on YouTube, Missy and Claire realize that they’ve opened Pandora’s box and much more than they ever imagined has come out. Not only are their identities called into question, but so is the future of everyone involved.

In this riveting, heartrending story by thriller author Caroline B. Cooney, the truth changes the lives of three families—as the bonds of blood must withstand the strains of long-hidden secrets that are at last revealed.
