K-Girls Plus One: Kylemore Abbey School (K-Girls, cartea 2

Would you let someone die if you could prevent it?
Teen Alice and ghost Ruth's special bond permits them to explore days of Kylemore Abbey's past, when their school was a Victorian castle and estate owned by the ill-fated Henry family.
But such adventuring has its consequences.
With the arrival of an illusive matron, two-faced twins and the mystery of a new haunting, life in second year gets a lot more complicated.
Of one thing Alice is sure, being a K-Girl is never dull, especially when you can time-travel.
