Hattie's Horse by Janet Muirhead Hill
In the early spring of the pandemic year, 2020, thirteen-year-old Hattie is sent to Montana to live with her grandmother on a cattle ranch. Her school has shut down, and her parents, both doctors, believe Hattie will be better off away from the city to do her remote learning. With a well-trained cow-horse that is also a trained barrel racer, Hattie feels like she's in heaven. All that can change rather quickly with the discovery of a runaway boy, the abduction of her aunt, and constraints and threat of the virus.
