I actually read this book a long time ago, but I was reviewing it to see if I would want to use it at story time. Although I don't want to, I still think it's an important book in the collection. It's the only picture book I can think of that tells kids how donor-conceived kids are created. In this case, Zak has two moms. I'm sure this situation is becoming more and more common, and I'm surprised I don't see more books about it.
