I read this book a few years ago
Mm Wolf a young wolf is being kept prisoner either in attic or celler by wicked alpha no one other than the inner circle know he's there .
When he isn't recovering from a beating and healing he paints which the alpha has been selling.
He eventually get found and the pack are shocked when that realise he's been there all the time and has been painting them.

Mm book no 2
Can't remember much but this book is within last couple of years
Young virgin was taken off the street by pimp but has refused to sell himself so pimp thinks that the young man believes he's better than everyone elsa .
I pretty sure he tries to runaway but pimps been watching him rape him and teach him a lesson he stabs him in his ear bursting his inner ear drum warning him he will do same to other ear and more if he ever trys to run again ( well something like that not much I know but at the time I had to put book down and decided to come back to it at a later date as it made me cringe).
