Light Most Hateful by Hailey Piper

Three years after running away from home, Olivia is stuck with a dead-end job in nowhere town Chapel Hill, Pennsylvania. At least she has her best friend, Sunflower.

Olivia figures she'll die in Chapel Hill, if not from boredom, then the summer night storm which crashes into town with a mind-bending monster in tow.

If Olivia's going to escape Chapel Hill and someday reconcile with her parents, she'll need to dodge residents enslaved by the storm's otherworldly powers and find Sunflower.

But as the night strains friendships and reality itself, Olivia suspects the storm, and its monster, may have its eyes on Sunflower and everything she loves.

Including Olivia.
