In Gap Mountain, California, everyone knows about fire season. And no one is more vigilant than 18-year-old Hannah Warner, the sheriff's daughter and aspiring FBI agent. That is until this summer. When Hannah and her best friends accidentally spark an enormous and deadly wildfire, their instinct is to lie to the police and the fire investigators.

But as the blaze roars through their rural town and towards Yosemite National Park, Hannah's friends begin to crack and she finds herself going to extreme lengths to protect their secret. Because sometimes good people do bad things. And if there's one thing people hate, it's liars.
