I absolutely love Zsadist. Him and V are my favorite characters in this series. I've lost count of how many times I've re-read these books.
Zsadist is one hard ass alpha male. His past is horrendous which is why he's always so cold and can't bare to be touched. This all changes of course after he rescues Bella. He's still withdrawn and cold but thaws....slowly. When they are laying in bed and he tells bella he's never had a kiss before...... omg I wanted to jump in the book and ravish him lol. He was so vulnerable then. Or when he scrubbed his wrists raw because he thought he was dirty. One of my facebook Z quotes from the book has to be “I was dead until you found me, though I breathed. I was sightless, though I could see. And then you came...and I was awakened.” it gives me goose bumps everytime I read it. Definately a must read. Such an emotionally brilliant book
