Kylemore Abbey School, book 2: K-Girls Plus OneLydia Little

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.
