The Four Season's Series: Unknown

Fifth book of The Four Season's Series.

Four girls travel around the globe to enrol at the Academy for Elemental Whisperers. The Academy is a secret association of people with special abilities, such as the ability to control fire, water, air or earth. They teach there students the history of the elements, how to control and use them for good and defence, and the dangers of having such a powerful gift. The Academy is hidden in the Elemental World, a separate universe from the Human World where hunters are wiping them out to extinction and taking them into to study like lab-rats.

Jessica Andrews, Astrid Torres, Jade Brooks and Shayla Hunt are four eighteen-year-old girls, that arrive at the school, all with their own private back-stories (In Books 1, 2, 3 and 4 of this series). All of them have a secret that they struggle to keep hidden from each other, since they all reside in the same dorm. Connections are made between one another, but what happens when secrets are revealed? They all have to join up to protect one another from the hunters and students/staff of the school, because everyone's out for them.

And they're rare power.
