If You Break by J. Rose

IT IS OUR SECRETS THAT DEFINE US. ESPECIALLY THE ONES THAT GET YOU KILLED.
Lexi spent her life in the shadow of misery, subjected to years of mindless abuse and degradation. After her tragic and brutal death, her story should have been over. She had found peace, at last.
But the universe had other plans.
Forced back into a body she longed to escape, Lexi is initiated into the world’s best kept secret. The shadowy society of The Redeemed. A motley collection of lost causes brought back from death by a mysterious force, known as the Vitae.
It is a fresh start, but this second chance does not come without a price. Lexi will be tested, forced to confront the trauma of her past and the danger of her present.
Because a war is brewing beneath the surface and every good army needs a survivor.
All she needs to do is stay alive, and somehow keep her fragile heart intact against the two men determined to claim what is left of her soul.
