Trust Me, by Noa Leibson

Kori is a blogger. The kind that would rather be inside blogging pictures than going out with friends. Despite being the wealthiest girl in Winslow Woods, she never takes anything more than she needs and is perfectly satisfied with a book and wifi. But something happens she only ever blogged about. Sickened, mutilated people walking through town trying to attack the normal. Zombies. Without an explanation, she’s brought on a ride with a mysterious boy named Artie who is desperate to bring them both to safety. But a journey like that is not so easy.
