The bull shifter, Ryan, and his human mate, Caleb, have made a good life together. Alongside Caleb's mother, Mandy, they run an animal rehabilitation center on their ranch. Ryan has become the honorary uncle to two young bull shifters, and Caleb is proud at how well his mate has acclimated to the human world. For Ryan, he's found the family and the peace he's long craved, and he's determined to keep it by whatever means necessary. But their quiet lives are disrupted when Caleb's aunt-Chief Hera of the US Agency-visits. And she brings a dire warning: the Knights of the Dawn want Ryan's blood. After losing someone precious to them during a skirmish with the knights, Caleb spirals into grief, and Ryan must work through his guilt and sorrow to care for his mate. A task made easier when Hera stays with her nephews, sharing their heartache. After they retreat to Haven, Montana, they begin the long process of healing. Unfortunately, Haven is in a state of unrest, and they are sucked into shifter politics that threaten the safety of the community as a whole. Meanwhile, the knights still need Ryan's blood, and he can't hide forever. Note to readers: Caleb and Ryan first show up in Love is a Whirlwind. While many of these books can be read alone, for full enjoyment please read previous books in the series, as this one does have many cameos and character resolutions.
