Her whole life it had just been the two of them. Before her mother's last breath, she gave Camille the information she had craved her entire life: the identity of her father. Daring to contact him, Camille was welcomed by an entire family she never knew existed. But nothing comes without a price, as she discovers when her family claims a legendary heritage tracing back to a Centaur touched by Zeus. As she learns the secrets of her Centaur bloodline, she is drawn into a forbidden love with Drake.

Camille and Drake are on the run from the head of the Centaur Council, seeking the mythical pasture of Thessaly and a family heirloom that may keep them safe. As their journey progresses from the rolling hills of Ireland to the snow covered forests of South Dakota, Cami learns more about her mother's secrets, including a twin brother and a Centaur legacy that puts a death warrant on her entire family.

The Centaur world is rocked as news spreads of the Lost Herd, Camille's existence, and her Centaur protector. A death order against Camille's father and family sends all into hiding. Camille and Drake leave the country pursued by the Lost Herd as well as by Centaur Council enforcers. Camille's twin brother, Cameron, is manipulated by the Council Head and is quickly becoming her newest enemy.

Cami and Drake's honeymoon is cut short as they escape attacks by the Council Enforcers and head to South Africa for the meeting of the Centaur Council, which has ordered a death sentence on Cami and all members of the Lost Herd. The Council Chairman is her grandmother, her most dangerous foe. Surrounded by family and friends, Drake and Cami face the Council, Cami's power-hungry uncles, an ambitious twin, taking the battle all the way to Zeus to attempt to win the freedom of the Tak herd.

After two years on the run, the novelty of traveling the world as fugitives has lost its luster for Jessica and Daniel. Jessica's family has promised her to a pure-blooded centaur despite her love for Daniel. Camille proclaimed that arranged marriages were a thing of the past, but tradition runs deeper than laws. If they want a shot at a life together, Daniel and Jessica must face off with her family and the family she has been promised to. Will the magic in their veins deliver a safe passage to the future, or will it be too diluted to save them from the present?
