The Charmed Children of Rookskill Castle — Janet Fox

Rookskill Castle has many secrets. Some you'll find Some will find you.

Twelve-year-old Katherine Bateson believes in a logical explanation for everything. But even she can't make sense of the strange goings-on at Kookskill Castle, the drafty old Scottish castle-turned-school where she and her siblings have been sent to escape the London Blitz. What's making those mechanical shrieks at night? Why do the castle's walls seem to have a mind of their own? And who are the silent children who seem to haunt Kookskill's grounds?

Kat believes Lady Eleanor, who rules the castle, is harboring a Nazi spy. But when her classmates begin to vanish, one by one, Kat must face the truth about what the castle actually harbors -- and what Lady Eleanor is -- before it's too late.
