About the book
"The Wife Project is complete, and Don and Rosie are happily married and living in New York. But they're about to face a new challenge because--surprise--Rosie is pregnant. Don sets about learning the protocols of becoming a father, but his unusual research style gets him into trouble with the law. Fortunately his best friend Gene is on hand to offer advice: he's left Claudia and moved in with Don and Rosie. As Don tries to schedule time for pregnancy research, getting Gene and Claudia to reconcile, servicing the industrial refrigeration unit that occupies half his apartment, helping Dave the Baseball Fan save his business, and staying on the right side of Lydia the social worker, he almost misses the biggest problem of all: he might lose Rosie when she needs him the most"--

“I actually liked this more than the first book, The Rosie Project. Doesn't look like this will be a trilogy and it would be fitting if this series ended with this book, since it had a good ending.”
“The first book is better but this was cute”
