Crispin Books has recently released The Dress-Up Mirror.
This mystery novel for children aged eight and up is a sequel to Shadow Island.
In my experience children love ghost stories and suspenseful mysteries, and I wrote these books and other collections of ghost stories (The Fresh Grave, The Ghost of Honeymoon Creek, and Dripping Blood Cave) for my own children. And I was understandably delighted that other children really enjoyed the stories, too.
