Winter in June (Rosie Winter Mystery #3)
Kathryn Miller Haines

But being a greasepaint soldier isn't as easy as they had hoped. Not only are the cast members surly, the schedules inhumane, and the housing conditions primitive but they also have to travel with a major—and majorly difficult—Hollywood star. But none of that is as bad as living in a war zone, and when tragedy strikes, Rosie and Jayne are left wondering if they are being targeted by the enemy or if something far more sinister is afoot.
