Hate rythmes with pain [English version]

Kelsey Miller could have been a normal young woman.
Yes, she could have. But fate decided otherwise.
One day, she finds her friend, Lily, half-dead in her home and, in a haze of rage and distress, she tries to take the law into her own hands, which results in the "ability", or curse, to transform into a cruel, ruthless psychopath at a moment's notice.
Aided by Megan Avona, an undercover soldier, Kelsey tries to track down Lily's alleged attacker, and realizes that it's all connected, in one way or another, to her.
But is she really ready for the truth?
