Six of Sorrow — Amanda Linsmeier

Sixteen years ago, six girls were born on the same day -- and now, on their birthday, one of them is missing. From the author of Starlings comes a story about small-towns, friendships, and the terrifying things your parents don't tell you, perfect for fans of Yellowjackets

For most of her life, Isabeau and her five best friends were inseparable -- amazingly enough, the six girls even share a birthday. Then a rift caused their friendships to fracture, and Iz lost everyone except Reuel.

Until now. The morning after their sixteenth birthday, Reuel is missing. She's gone for two days, and when she reappears, there's something wrong with her. She's sick. Really sick. And she doesn't remember anything that happened while she was gone.

Then it happens again. A second girl from their sisterhood disappears and comes back wrong. Now all the girls can feel it. Something's been waiting for them, and it's only a matter of time until they're all taken.
