Having read and enjoyed The Man Must Marry, I was happy to spot Tempt Me If You Can on the shelves. I really enjoyed the Sinclair family's dynamic. Unfortunately, the family plays a lesser role in this book.
Ben Sinclair receives an anonymous note telling him he has a son living in rural Maine that he never knew existed. After confirming the boy is really his, Ben hotfoots it out to Maine--incognito--while he figures out what to do. Neither Emma or Michael are fooled by Ben's slightly older appearance or different name. But there's an initial period where they pretend to be fooled which adds a little confusion and tension.
