There's no rulebook for living on a veterinary farm for sick animals -- unless you make one yourself!
Eleven-year-old Charlie Dembinski likes to keep his life organized and quiet. This is a challenge when you live on a farm where your mother runs a veterinary clinic for the local livestock, neighbors' pets and sometimes rescued wildlife. To complicate Charlie's orderly life even further, his mother hires a bookkeeper to live on the farm who brings along her daughter, Amy Ma. And Amy is anything but quiet! Her constant questions and attempts to spend time with Charlie really bother him, and he doesn't understand why the adults seem to like her so much. But when a neighbor's beloved dog gets sick with a mysterious illness, Charlie realizes that Amy's outgoing approach might not be all that bad.
This is the first book in the Charlie's Rules series.
