Every morning, Carmen Hart pastes on her made-for-TV smile and broadcasts the weather. She's the Florida panhandle's favorite meteorologist, married to everyone's favorite high school football coach. They're the perfect-looking couple, live in a nice house, and attend church on Sundays. From the outside, she's a woman who has it all together. But on the inside, Carmen Hart struggles with doubt. She wonders if she made a mistake when she married her husband. She wonders if God is as powerful as she once believed. Sometimes she wonders if He exists at all. After years of secret losses and empty arms, she's not so sure anymore.

Until Carmen's sister-seventeen year old runaway, Gracie Fisher-steps in and changes everything. Gracie is caught squatting at a boarded-up motel that belongs to Carmen's aunt, and their mother is off on another one of her benders, which means Carmen has no other option but to take Gracie in. Is it possible for God to use a broken teenager and an abandoned motel to bring a woman's faith and marriage back to life? Can two half-sisters make each other whole?
