==Book Description==
Jena Calhoun needed a summer job before completing her degree. Travis Larson needed someone to care for his two young daughters while he managed his law firm. The arrangement was made out of convenience -- after all, Jena is not his type of woman. And Travis isn't her type of man. — A romantic interest slowly develops between Travis and Jena. A misunderstanding throws them together as "man and wife" for a dinner party, and the idea seems to gain merit each day. Travis likes Jena's steadfast devotion to his daughters -- and to her Lord. But Jena knows he doesn't share her faith. She senses that he still harbors a deep sorrow over his wife's painful death.
Jena prays that Travis will come to Christ and find healing for his emotional wounds. Now, she must guard her own heart... Dare Jena hope to ever be more than Travis's summer girl?
