Stars of Heros spans from the 19th Century to the 26th Century and beyond. The series title is a tribute to, and a word play on, the main themes in the books: horses, space, family, and heroes. Whether ordinary people or aliens, these heroes try to make a difference on their home world.

In Spirit of the Lone Horse, the first in the Stars of Heros series, we are introduced to Jo Mason and her family. Jo is the commanding officer of a large mounted band base. Thanks to a horse almost killing her, she is terrified by the noble creatures she once loved. Meeting the rogue stallion's son, she is faced with the choice of running away from her fear or taking back control of her life. Her decision begins an adventure that weaves a tapestry through past mistakes and regrets, present circumstances and consequences, and future hopes and dreams.
