The first in James Spurr's Historical Series, Sworn for Mackinaw begins in pre-war Detroit with business and family man Oliver Williams and his brother-in-law, Captain William Lee. Both men stake their futures on a new venture: the fast sailing sloop Friends Good Will. When war erupts, it causes tension between friends, strains on blood bonds, and the unforeseen peril of carrying a secret cargo.

The challenges of war continue long after the last shot is fired. . . Wary of the very peace he seeks, Captain James Lee struggles with the circumstances of his father's death. Marie LaPointe struggles with her past and fears trusting the future. Oliver Williams embraces his future, but was it bought with the life of his old friend? And Bemose wishes for nothing but the healing of her family.

Two strong-willed men, related through marriage, bound by friendship, separated by war, face the challenges of battle on the Great Lakes during the War of 1812. Captain William Lee and Oliver Williams become embroiled in the cauldrons of the greatest battles to ever take place on the inland seas. Join them and a young Master Commandant Perry as he rises to become one of America's greatest heroes.
