Riley Andrews had a perfect life: a beautiful son, a rewarding career, and a husband who loved staying home-until one day when he didn't want to anymore. Riley quickly transforms from working-woman to stay-at-home single mom. Before long, she realizes a successful new life is through joining the PTA. Fighting off parental miscues, her soon-to-be ex-husband, and the Association's hierarchy, Riley realizes she's in over her head. As hard as it is to admit, she needs help. Enter Sam Aldin. A widower and the only dad in the PTA, he knows what it feels like to be an outsider. Riley and Sam bond instantly as they realize the women of the Hubbard School PTA are not exactly thrilled by newcomers. Their power-play decision to chair the annual fundraiser might turn the whole organization upside down, and just might make Riley see beyond her way of doing things. One thing's certain, for a woman like Riley to survive the PTA, it sure doesn't hurt to have a man like Sam in her corner.
