It's a battle of the bio-synths as Max, Zack and Tinga's plan to stop Lydecker from snagging Tinga's son pits them against Madame X's newest weapon---a brainwashed Brin. But when a double-cross puts them all in danger, it becomes clear that someone at Manticore is keeping secrets about the future of the X-5 project.

Madame X's twisted plan for Max forces Lydecker into an unholy pact with a pack of his former "kids" to bring down Manticore. But when things go tragically awry, Logan must make a life-altering choice that could put Max back into the hands of the enemy.
