The Awakening by L C Ainsworth

15 year old Diana and five of her friends are starting a new school, and they have one mission: find out why strange things have been happening at J.C. Maxwell Boarding School. What Diana did not expect to find was a series of unexplained murders and the staff acting strangely.

Soon, Diana and her friends find themselves at the centre of a dangerous conflict, where everyone is more than what they seem, and no one at J.C. Maxwell is there for the reason they claim to be.
