10 Hours to Go by Keely Parrack

Lily wants to get home. Her friends want to get even.
Lily needs a ride-a fire warning in Oregon has cancelled her train home to California. Her ex-best friend, Natasha, has offered to pick Lily up on her way back from Portland, though they're barely on speaking terms. As it turns out, Natasha's also giving a ride to Elke Azizi, the girl Lily got expelled from their school four years ago. Elke hasn't forgotten, and neither has Natasha.
It's getting tense in the car, and it's not just about the past. There's smoke in the air, and with the wildfires nearby, staying on the road is becoming riskier by the hour. When Natasha and Elke decide to take a detour, Lily hopes it'll get them out of danger. She has no idea, though, what her former friends have planned for her.
But as night comes, the plans change again when it becomes all too clear that leaving the main road was a mistake. Now the three of them are trapped in the woods under a burning sky, with no easy way out. To survive, Lily must depend on Elke and Natasha-but after all that's happened, can she trust them with her life?
