FLINTRIDGE, MICHIGAN.

It's Kathleen O'Halloran's hometown. It's also Slater Kowalski's. And it's a town divided.

Kat and her exuberant family live in the part of Flintridge known as the Hill; Slater is from the Ridge.

Slater is the president of Flintridge Motors; Kat's family workds for his rival. Ridge and Hill have always functioned as almost separate communities, but the boundaries start to blur when Kat goes to work for Slater's company -- and even more when she falls in love with him.

Still, the course of love is far from smooth. Slater's exciting new project is being sabotaged. From within or without? He needs to know, and so does Kat. Then there's the strange behavior of Kat's father and Slater's dad, who have unexpectedly become allies. And what about Kat's brothers, who are determined not to welcome Slater to the family?

Sabotage and secrets, old rivalries and new hopes. Can two people in love create one town...and one family?
