Maggie Blount, divorced mother of two and California physician, puts her private practice on hold when disaster strikes. Doctors on Wheels takes her and Alex--Maggie's professional and romantic partner--wherever they're needed. After rolling into rural Louisiana in the wake of a category five hurricane, Maggie immediately bonds with two sisters and their puppy, all orphaned by the storm. It's enough to break Maggie's heart, and she's not leaving them behind.

Feeling blessed and looking forward to their new foster home in affluent Vista del Mar--a world apart from the one they've known--Jean and Rose are polite, appreciative, and humble. Frankly, they're the polar opposite of Maggie's own self-involved teenage daughters, Willa and Gemma, who resist this intrusion by strangers into their privileged lives. Soon enough, Maggie's new blended family is in chaos.

Teaching Willa and Gemma about gratitude and empathy will be hard enough. Maggie must also admit her own role in their entitled upbringing, undo the damage, and anticipate the needs of all four girls and a puppy, all amid faraway natural disasters and those closer to home.
