Overgrowth by Mira Grant

Mira Grant (Seanan McGuire's pseudonym) combines body horror, 50's monster movies and alien invasion in this deliciously creepy novel.

Anastasia Miller has been insisting to anyone who asks that she is an alien in human disguise since she was 3, most people take it as a somewhat amusing personality quirk, but we soon find out that it's not just a quirk. When an alien signal is picked up, Anastasia realizes that her family is coming for her and the others on Earth – and they may not be very friendly.

Absolutely recommended, as are all Grant's works no matter what the name on the cover is. Grant does a lot with subtext around found family, children's feelings and needs and listening to same. There's a revelation close to the end of the book that will break your heart, it did mine.

I received an ARC copy from NetGalley in exchange for my honest opinion.
