Can not remember book title etc.think it could have been 1st bk in series.

Mc is at home looking after his dying mother everytime he goes outside he feals like he's being watched.
After his mother dies he gets taken.
He wakes tied up and being told by a alpha he's is going to be turned,be the lowest of low he gets passed around every member of the pack after the alpha until their body fluids turn him.
Spoiler - he ends up being stronger than the alpha ,he goes back home taking half the pack with him starting his own pack.
