Novel in Tapas

I was reading a novel on Tapas and suddenly it disappeared. Can someone help me?
It was about a boy named Key or Kay, that lived in a cage in a red room. If he could pass a labirynth, his owner said he could go home, but he never ger to pass. The owner was a very bad guy, who would punish Key if he cried, if he disobeyed, if he did anything, basicly. Then, the owner gets out with him, and he finds out that the owner's name is Jeremy - i think he was already 12 years captive, but he never know the name. And... I don't remember anything else, and I've looked all around Tapas to find it again amd didn't. I don't know the name of the novel, or the author. I think it was in Tapas. It's the only place I know to read novels...
