In 1904, sixteen-year-old Maggie Bennet is poised for her glittering Newport debut when her world collapses. Her mother vanishes under mysterious circumstances, leaving behind scandal and whispers of madness. Instead of a summer of gowns and dances, Maggie is swept west with her father to the untamed wilderness of Yellowstone, where he believes there may be answers. Amid geysers, steaming pools, and mountains that test her courage, Maggie discovers more than clues to her mother's fate. She meets Tom Rowland, a local boy whose quiet strength and loyalty challenge everything she thought she knew about class, love, and her own heart. Drawn to him in ways she never expected, Maggie begins to see that the wilderness-and Tom-may hold the key to the freedom and belonging she has longed for. As secrets surface and dangers close in, Maggie must confront both the truth about her family and the desires of her own heart. To claim her future, she must decide whether to cling to the life she has always known or embrace the unpredictable, untamed one calling her name. Faithful is a sweeping YA historical novel of romance, mystery, and self-discovery, set against the breathtaking backdrop of America's first national park.
