Blade Petals: Black dahlia

"WARNING: CONTAINS DEPICTIONS OF VIOLENCE AND MATURE THEMES"
In this gripping mystery/thriller, twin sisters Elora and Elana are brutally torn apart on their sixteenth birthday when Elora is abducted and forced into sex slavery in Mexico. Elora's harrowing experience transforms her into a ruthless serial hunter, driven to annihilate everyone involved in the sex trafficking ring.
Ten years later, Elora's killing spree spills into the US, where her twin sister Elana, now a determined detective, is tasked with tracking down the elusive serial killer. As Elana delves deeper into the case, she uncovers a dark web of secrets and lies that threaten to destroy everything she holds dear.
Will Elana's duty as a detective prevail, or will the bond of sisterhood prove stronger? Is Elora still the sister Elana knew, or has her decade long odyssey carved her into a different person for whom there's no redemption.
Revenge though, is an ocean that drowns both the pursuer and the pursued.
