My 10 year old daughter reads the creepy and scary books I have featured on this page and she loves them! She began reading these books about a year ago starting with the My Sister The Vampire series. She enjoyed those books so much that we found other series that had similar dark and scary themes and she enjoyed those books as well. She has even loaned some of these books out to her friends and they have liked them, too. My daughter is not a Goth girl or anything, but she does like wearing skull t-shirts and she had a Pink Skull Party for her 9th birthday. So, maybe she does have a bit of darkness in her somewhere.
The children's book series on this page include My Sister The Vampire, Bedeviled, Supernatural, Poison Apple, Creepover and Monster High. If your daughter enjoys this genre as well and is too young for books such as Twilight, I highly recommend these books for girls age 8-12.
