The Hamilton Kids' mystery series features thirteen-year-old Jaime and her two brothers: Sam 11 and Danny 9. They live at the foot of a huge hill they call Spider Mountain because it's inhabited by all kinds of creepy, crawling creatures, including trap door spiders and tarantulas.
They wonder who lives in the mysterious house at the summit. The dark house is surrounded by evergreen trees and a wrought iron fence enclosing four large vicious dogs. One day they climb up the mountain and their lives are changed forever.
The next book in the series is The Ghost of Crimson Dawn.
