Pru Reynolds is the reliable sister, the one everybody depends on, so of course she's the natural choice to adopt the foster child her late mother left behind—even if she's got no one to help share the load. At thirty, becoming the mom of a teenager means big changes, and Pru's ready to do whatever it takes to adopt Ari. But before she settles down she wants one thing for herself. Enter Flynn Bohannon, the sinfully sexy Irish musician in town for her sister's wedding. He's led the kind of life Pru can hardly imagine. He's no one's idea of stability, but he's the perfect guy for a crazy fun fling before her life changes. When Pru proposes a no-strings affair, Flynn's all on board. But when unexpected complications endanger the adoption, the two find themselves in a phony engagement. Now they have to convince a sharp-eyed, skeptical social worker, a teen who's too smart for her own good, three dubious sisters, and one protective brother-in-law that Flynn's willing to give up the gypsy life and settle down. But in convincing everyone that this relationship is real, will they convince each other as well?
