Book excerpt: Double The Trouble Parenting is hard enough when Dad has to be a mom, but widower Luke Gregson has twins—boy twins, Aiden and Caden. As a navy SEAL, Luke saw plenty of action, but nothing could prepare him for trying to raise two eight-year-olds alone. Parenthood is not for sissies. Maybe that's why the boys have set their eyes on a certain new candidate for Mommy… Officer Carmen Delgado seems tough enough to handle anything—including Aiden and Caden! She adores the rascals. Her feelings for their heroic father, however, are complicated, and her tragic past has her heart on a seemingly permanent lockdown. Could two mischievous, persistent boys and their overwhelmed, sexy daddy be the ones to finally set Carmen free?
