Deadly thorns

"Mackenzie can't lose another friend. Even if he doesn't want to be found... In the aftershock of Amy's death, Mac knows Kyle is terrified he'll hurt her in some way and has left Hemlock to enrol in one of the Lupine Syndrome Registration Bureau's rehabilitation camps. But the camps are rumoured to be torturous and unsafe and Mac is desperate to find him before it's too late. She finally tracks Kyle down, but their reunion is cut short by a Tracker raid. Now Mac and Kyle are trapped inside the electric fences of camp Thornhill where inmates keep disappearing. Mac knows that something sinister is happening, and as she uncovers dangerous secrets buried within the walls of Thornhill, she realizes that the risk to the people she loves is greater than ever before."--Back cover.
