Vampiric Vacation : (The Sinister Summer Book 2)

The spooky summer adventures of the Sinister-Winterbottom twins continue in another gothic mystery: can Theo and Alexander solve the secret of the Sanguine Spa? The second book in the new Sinister Summer series by #1 NYT bestselling author Kiersten White, called "perfect for fans of Lemony Snicket, Edward Gorey, and Roald Dahl," by Shelf Awareness.

After leaving Fathoms of Fun, the kids are on their way to the next odd summer destination their aunt has chosen for them. This time, they find themselves dropped off at the Sanguine Spa in the “little Transylvania Mountains.” There they meet the owners: Mina, her mysterious little sister, Lucy (who is extremely pale, can’t go in the sunlight, and has an affinity for hanging upside down from the ceiling), and their intimidating guardian, the Count.
