A Heart of Little Faith by Jennifer Wilck

Lily Livingston is a widow raising her six-year-old daughter, Claire, in New York City. Devastated by her husband’s death three years ago, she’s in no hurry to fall in love again. Besides, trying to balance her career with motherhood leaves her little time for romance.
With a wheelchair instead of a white horse, and a vow against falling in love again as his armor, Gideon Stone is the last person Lily expects to sweep her off her feet. But when a business agreement forces the two of them together, that is exactly what happens. As they navigate the minefield that fast represents their relationship, can either of them overcome the obstacles to find true happiness in each other’s arms?
