I have gotten a lot farther in Death Sentence by Alexander Gordon Smith, and now I am almost finished with it now, but anyways now that Alex has fallen asleep he has these weird night mares and when he wakes up the warden ask him about his dreams then answers his own question. Then Alex falls asleep and has more nightmares, then later on you find out that Alex has been blind because of the iv pumping that black liquid into his veins. After a while he can open his eyes but he realizes that everything is silver and he can see in the dark like a black suit another set of people that have been mutated by the weezers and the black liquid. Then the warden starts talking to Alex trying to get him to accept his fate, but right before he does he remembers his name and starts screaming I am Alex Sawyer over and over.
 Next he is forced to watch a non stop film of people and animals being killed with his eyes pinned open so he can't close his eyes.  After a while a black suit tells him to give in it will be easier on him and eventually he does.  He goes into surgery on his legs, which are packed full of steel cable like muscles after the surgery and then a little later on he goes in for another surgery and another after that.
When he goes in for surgery on his arms some thing happens, a creature breaks loose from a surgery room and starts beating up on these (super humans)  black suits. Thats when Alex remembers who the creature is even though whoever it once was is now unrecognizable and he starts yelling at it,  you are Gary your name is Gary and the thing drops him after a shock from a cattle prod or some thing.
 Now that he remembered the creatures name he new his, and the warden knew that and had him watch that film again but when Alex was passed out the weezers did some more surgery on him. Later he forgot his name again and the warden knew this now after some questions and Alex once again falls asleep. When he wakes up he is chained to a wall. Which he rips from the wall to escape the water exploding from the pipe as he hits a dead end with the water flooding the tunnel behind him fast, he leaps up into a tunnel above him and reaches a road block. he starts to punch the steel hatch blocking his path and eventually it goes flying and he escapes death. then he is knocked out, but when he wakes he has to fight off some giant rats. He wins the battle even though he was out numbered a million to one, and he passes the wardens test.
