Grave Errors by Carol J. Perry - This is another book that takes place around Halloween - in Salem, no less - and with the spooky cemetery, arched back cat and full moon it looks like the perfect Halloween read.
The Enchanted Castle by E. Nesbit - The colors on the cover just scream fall to me though the book really doesn't have much to do with the season.
Death in Abstract by Emily Barnes - If I remember right this book actually takes place during the winter but with all that fall foliage in the back the cover at least says fall.
Send in the Clowns by Julie Mulhern - Another fall foliage book and this one involves a masked figure lying in a leaf pile. The book has a haunted house, trick or treating, and of course clowns!
The Haunting of Hill House by Shirley Jackson - Everything about this book is Halloween-y. The creepy house, the bare branches and the glowing orange sky.
Cider Brook by Carla Neggers - The barn, the leaves, the title. Really the word "cider" is enough to make me think fall.
Hallowe'en Party by Agatha Christie - The pumpkin, the color, the full moon and then there's the title!
A Killer Crop by Sheila Connolly - The whole cover just screams fall harvest (even without looking at the sign!). It makes me want to sip apple cider and pick out a pumpkin.
So apparently Halloween themed covers are a strong pull for me when looking for covers that say fall. What do you look for? Any favorite fall covers?
