Gracen gets better with every book, and with her fourth Harrison siblings contemporary (after Happily Ever After), she hits the emotional jackpot with a multilayered tale of a rich yet down-to-earth woman and an intelligent, caring man who can't forgive himself for past mistakes. At a joyful Harrison Christmas celebration, Tess Harrison feels alone—her brothers are all married and have children, and she's still single. She decides to have a baby on her own, heading to the family's house in Aspen, Colo., to dodge unwanted questions. Meanwhile, after a disastrous divorce in New Orleans, Logan Carter goes home to Aspen, planning to take care of his dying mother and work as a house caretaker—one whose duties involve the Harrison house. Logan is honorable and generous, and he still blames himself for not saving more people during Hurricane Katrina. He's got combustible chemistry with Tess but refuses to let himself fall for her. When Tess asks him to be her sperm donor, Logan is floored, and it changes their relationship forever. Gracen's lyrical prose, combined with heartbreakingly perfect characterization and a stellar cast of supporting players, makes this one a keeper. Agent: Stephany Evans, Ayesha Pande Literary. (Dec.)
