Fire (Akasha, #3)

Elemental magic is a weapon of power, on both sides of the war.

The Seven has another leader, Kaitlyn is a new mother, and everyone is busy building their armies. During one battle, the secret to Akasha is discovered, and the race to master it is on. With all eyes on the prize, what matters most gets left behind. It is up to Kaitlyn to preserve the planet in the wake of the pure destructive power of Akasha, and the humans who wield it.
