A kid walks into your bookstore and . . . Guess what? He's your son. The one you put up for adoption eighteen years ago. The one you never told anyone about. Surprise! It's a huge surprise to his adoptive mother, Monica, who thought she had a close relationship with Matthew, her nearly adult son. But apparently, he felt the need to secretly arrange a vacation to Cape Cod for the summer so he could meet his birth mother . . . without a word to either her or his dad.
