Charlotte Crowninshield was born into one of the finest Boston society families. Now she’s on the run from a brutal husband. Billie MacTavish is the oldest of nine children born to Scottish immigrants in Nebraska. She quit school in the sixth grade to help with her mother’s washing and mending business, but even that isn’t enough to keep the family afloat. Desperate, both women join the ranks of the Harvey Girls, waitresses who serve in America’s first hospitality chain on the Santa Fe railroad. Hired on the same day, they share three things: a room, a heartfelt dislike of each other…and each has a secret that certainly will get them fired. But when they’re sent to work at the luxurious El Tovar hotel at the Grand Canyon, Billie struggles to hide her young age from would-be suitors, and Charlotte discovers the little-known dark side of the national park’s history.
