Spooky Season (Bramble and Maggie #3)
Halloween is a huge deal to readers in this age group, so it makes sense for a book in an early reader series to concentrate on this holiday. Horses are also undeniably attractive, so this is a great choice for elementary students. I remember reading books like Gus Was a Friendly Ghost and the Georgie series year round. The illustrations are attractive, and I liked that Maggie was always very responsible when it came to taking care of Bramble.
