It’s a fun little story about being proud of your differences.  Crispin is a young dragon who is at first horrified on his seventh birthday, when he’s supposed to start breathing  fire, to find that he breathes other stuff instead.  First his dad tries taking him to the doctor or school to solve the problem, then Crispin runs away to try to escape the problem, and then he befriends a young knight who tries to help him solve the problem, but in the end everyone realizes that being different isn’t necessarily a problem after all.  It helps that every time Crispin tries to breathe fire, whatever comes out instead happens to be whatever is most useful at that moment.  Dragons are always a hit, and this one is cute and conveying a good message.
