It's Halloween night when strangers come to Linden Street...and something dear to Olive goes missing. To what lengths will she go to get it back? Can she trust the strangers?

The stakes grow higher, the secrets more dangerous, and mystery and magic abound as Olive, the boys, and the cats uncover the true nature of the house on Linden Street.
