Sophie and Katy have almost forgotten that they're supposed to be mortal enemies - and now that they've persuaded Sophie's family that witches and witch hunters can be friends, life ought to be nice and straightforward! But it's not long before magic gets in the way again. Katy is still keeping Sophie's identity a secret from her parents; if they knew she was the daughter of a famous witch they'd demagick her for sure! And both girls are keeping their powers hidden from their other friends, a feat which is getting harder all the time. When they head off on a school trip, it seems they might have to finally spill their secrets. Can they make it back to Turlingham with their sorcery still under wraps?
