When a riot erupts in Built4's stein-building lab, the alpha stein Kee drags a submissive young lab assistant into his cage. Kee's been studying the human. Ben's sad eyes and slender form call to Kee -- urging him to equal parts lust and possessiveness.
Prisoner to the alpha, Ben surrenders to the stein's fierce determination and gentle seductions. He's long hated his job, feeling like a monster for following his boss's orders, especially once he's seen intelligence flickering in the alpha's green eyes.
If Kee's to escape, he needs Ben's help to learn about the world outside the laboratory -- a world full of people, sex and experiences Kee's only beginning to discover. And guilt-ridden over the things he's done, Ben can only forgive himself if the alpha forgives his sins first.
