Last winter I read a book called Belly Up By Stuart Gibbs. Belly Up is about this boy, Teddy Fitzroy (Teddy) It’s about a kid whose parents work at a zoo/theme park and later a animal is found dead so Teddy has to investigate the crime. He finds a friend to help him, she helps him weave through Marge the security guard and the whole entire zoo. Teddy has to make sure he is not found belly up before the mystery ends.
