The Sword in the Grotto (Araminta Spook #2)

Sir Horace is about to turn five hundred years old Araminta and Wanda need to find him the perfect gift. Araminta finds an ancient sword in a grotto hidden under her haunted house and it should be a cinch to get it. But she wasn't planning on the nasty surprise of a portcullis-trap and a rising tide in the grotto. Will Araminta and Wanda make it to Sir Horace's birthday party?
