Fairy Tale Detectives, part of The Sisters Grimm series, is a hilarious novel about two girls, Sabrina and Daphne Grimm, who are orphans. They have theoretically not relatives and have been tossed around to many foster homes. When someone who claims to be their "Grandma Grimm" shows up, the girls are a bit skeptical about following her to her home in Ferryport. But soon Sabrina and Daphne find out that things aren't always what they seem in Ferryport.
I think everyone should read this novel! It's a book that you will never be able to put it down!
