This is a book that had a good intention but it does have something that I would imagine might offend some people. I don't really see why they would call the sperm donor dad. I understand leaving with a single mom you need a father figure but a dad is not the person that gives the sperm whether it be the old fashion way or through a sperm bank. I understand the need to know where you come from but making that association I would imagine that there's a lot more children that have been conceived that way now a days and I would imagine as a parent and your teenager reads this how are you gonna explain to them that every situation is different and that having one parent is perfectly fine. Its good just has a lot of things that they really have to watch for because of their audience.
