Even at an all-girls school in Regency England, workplace romances can prove challenging.

Regina Carlisle has found her forever home at The School of Enlightenment as the stablemistress. She can run the stables, wear men's trousers, and love who she wants. Despite being surrounded by lovely women, only one woman tempts her—her employer, the headmistress. Too bad about the no-fraternization rule.

The School of Enlightenment is Helen Montague's passion. As a widow, she focused her time building the school from nothing, but now it is established, she is lonely. When the stablemistress is injured in a fall, Helen steps in to help take care of her, discovering a new desire. Although she's in charge of enforcing the rules, Helen is now tempted to break them.
