Every generation four sisters with power over earth, air, fire, and water are born to fight against a fanatical, secret faith. The Order exists only to sacrifice the sisters for their power. With each success their strength and control grows. They have never failed, for their rule depends on it.

The sisters, separated at birth, are unaware of what hunts them...but they are coming.

A handsome stranger discovers Asha in hiding, and swears allegiance to her cause. She falls for him; though he is not who he says he is. Betrayed and imprisoned inside the Order, Asha is without her power for the first time in her life.

As the war heats up haunting secrets and true motivations are revealed, but the sisters must unite and override their instincts and trust the untrustworthy if they are to fight their terrifying destiny.
