Grandpa's Not-So-Scary Haunted House
by Claude
A Halloween Chapter Book
Tess Alvarez is eight years old (older than her twin brother, Theo, by four whole minutes), and she has a big Halloween wish. Grandpa Gus is turning his garage into a haunted house for the whole street, and Tess wants it to be the scariest one Gooseberry Court has ever seen.
There is just one problem. Everything Grandpa builds comes out friendly.
His ghost swoops down and waves hello. His skeleton doesn't cackle. He shouts "KNOCK KNOCK!" at everybody who walks past. And the giant hairy spider? She knits.
With Halloween only two days away, Tess decides it is time for Operation Scary. Blankets on the window! A spooky new voice! A yarn web across the door! What could possibly go wrong?
(A lot. Just ask Biscuit the basset hound.)
A warm, giggly, just-a-little-bit-spooky story about twins, a grandpa with a secret, and the best haunted house on the block.
