The origin of X-23! Cloned from Wolverine's cells and ruthlessly conditioned by her harsh masters at the Facility, young Laura Kinney is the perfect assassin. But when she breaks free at last, can she rise above her training and killer instincts to forge her own path in the world? Or will the gallons of blood she has spilled drag her down? Follow Laura's journey of self-determination - including a search for family and friendship, her first meeting with Wolverine himself, her alliance with Gambit and a deadly clash with Logan's vicious son, Daken! But when memories threaten to overwhelm her, can Laura defeat the darkness within? Collecting X-23 (2005) #1-6, TARGET X #1-6, X-23 (2010A) #1, X-23 (2010B) #1-21, CAPTAIN UNIVERSE/X-23 #1 and DARK WOLVERINE #8-9 - plus material from TO SERVE AND PROTECT #2, THE ROAD TO HELL and ALL-NEW WOLVERINE SAGA.

Government-controlled killing machine. Child of the streets. X-Man. X-23 has lived many lives, but none of them have ever felt right. She knows she's a killer, but she's not sure she can be anything else. The X-Men offer her a home and help facing her demons, but she's done being someone's project. She wants to be her own woman, and she'll do it on her own terms. Leaving the X-Men's island home of Utopia on a mission all her own, she's already found trouble. Even with the mutant thief Gambit at her side, her past haunts her. With new enemies rising, can X-23 trust herself not to succumb to her deadly ways? Or is it all just in her head? Free of her chains, can this killer finally taste true freedom?
