==Book Description==
Caleb Jonas was long known as a drifter, his travels taking him throughout the west. But he has finally come home to the Wyoming Territory of his childhood. Feeling like a stranger, he socializes but remains distant, never willing to open up to anyone. Then Lydia Bennet moves to town, and Caleb seems to enjoy baiting her fiery temper. But he also tries to ignore the grip on his heart as he watches her mother push Lydia into the open arms of the local banker. Lydia speaks of peace through a relationship with God while she is also plagued by her own impetuous instincts. Caleb will keep coming to her rescue, but it could cost him the very life he has come to hold dear.
