This is getting a lot of love, but less from me because it contains one of my biggest pet peeves that I can't seem to get over, which is: when something completely extraordinary, unbelievable, or frightening happens to characters, they need to freak out. At least a little. Maybe kid readers don't really care, but it annoys me. 
 Otherwise, this covers scientific discovery, family relationships, and changing friendships quite nicely. There's plenty of humor in the family dynamics, which is fun.
