First One; The setting is middleages or earlier in a fictional europe(I think). the main character was raised by the last of the wyverns and was forced to fight the wyvern. ( I've only ever read the first chapter of this one)
Second One; Main character teams up with a computer virus and they join a survival game( or something like that) he never shows any supprise no matter what happens.
Third One; Main character almost dies in first chapter but is saved by a weird female docter that did some experiments on him. so he now have super strength (and maybe some other superpowers,.) he's forced to help her out with her animal clinic.
