Premonition — Elle Klass

The first book in a trilogy.

Maddie's parents flip when they find out she's failing science. That's her worst problem until she wakes up and finds they're zombies. Now she must escape them and her house. With nowhere else to go, and the keys to her parents' sailboat, she makes her getaway. Finding Bryce was a fortunate circumstance and the two take on zombies and set sail for parts unknown.
