Bags are packed, passports are updated, and it's time to travel to Scotland! Lela and Mae are so excited at the prospect of meeting their extended family and discovering how to break the curse on the coins, cauldron, and Florie. They've come so far since moving back to Tennessee, surely nothing else will go wrong. Hang on a minute... Bertha's all ready to go, complete with mysterious clear liquid-filled mason jars in her checked bag, but where's Harriet? Oh, crud. She's gone. Did something horrible happen to her? The twins can't possibly fly overseas until they find Harriet. The problem quickly turns into a fiasco when nobody can locate her. Mae is beside herself with worry and it's all Lela can do to keep her twin from going crazy. Ted and Joseph help all they can, in their supportive boyfriend kind of way, and the coven pulls out all the stops to find Harriet. Still, she's nowhere to be found. When Harriet finally resurfaces, she's full of information about their family, the curse, sin eaters and the world in general. If there's one lesson the twins have learned, it's that things aren't always as they seem. Harriet is about to give her family a big eye-opening, worry-filled adventure.
