Bestseller Pearce (Romancing the Rancher) launches a new series with a cute contemporary romance inspired by Three Men and a Baby. Marine Jen Rossi relies on her flaky ex-boyfriend Dave to take care of their one-year-old son, Sky, while she is away on active duty. But when Jen is delayed in her return, she learns that an impatient Dave abandoned Sky on a ranch in the Redwoods with military buddies she's never met. When she goes to retrieve him, she winds up stranded with the three marines-turned-cowboys, including handsome but taciturn Noah, who has bonded with Sky and is initially judgmental about Jen's parenting. Jen is attracted to Noah but refuses to make another romantic mistake, while Noah lusts after Jen but grew up with the responsibility for a large family and wants to avoid entanglements. They agree on a no-strings-attached fling, but that's not all that either really wants, and it will take all the cowboys together to work out a satisfying conclusion. Disillusioned Jen makes a refreshing heroine, but readers will need a high tolerance for grouchiness to understand Jen's choice in men (especially as there are two other equally strapping cowboys right there). Still, the domestic comedy and steamy sex scenes set this apart. Cowboy romance fans will be charmed. (Jan.)
