A Little Ray of Sunshine - Kristan Higgins - Bog

"A kid walks into your bookstore and says to you, 'Guess what? I'm your son.' The one you put up for adoption seventeen years ago. The one you never told anyone about. Surprise! His name is Matthew Walker, and he's come to spend the summer on the Cape with his parents. Why? Well, he wants to meet you before he heads off to college in the fall. Tiny detail: he didn't tell his adoptive parents about his plan. And while you hoped this day would come someday, you're so stunned, you actually faint. You're overjoyed (and stunned) and worried (and stunned) and you've yearned to meet him, but you didn't know it would be like this. Did you mention feeling stunned?"--
