In Bonnie Pega's captivating love story, a sworn bachelor falls for the most unexpected woman of all: an expectant mother.   When the tall, dark, sensual stranger walks into her Lamaze class with his pregnant sister-in-law, Liberty Austin's reaction is immediate--and exhilarating. Blame it on the hormones, but the newly single mom-to-be can't stop fantasizing about the seductive hunk who's all wrong for her. His name's Zachary Webster. He's a genius tech entrepreneur with big plans for his future. And they don't include marriage and fatherhood.   Meeting the woman of his dreams--a radiant beauty with soulful blue eyes--while she's carrying another man's baby might be the definition of bad luck, but Zac stopped believing in picket fences and happy endings long ago. So why is he finding it impossible to stay away from Libby . . . especially after he helps deliver her baby? Suddenly Zac is confronted with the toughest choice he's ever had to make: a lonely existence free of risk and heartbreak or a life with the family he's come to love.
