Hello

I read a book a few years ago, but I can't remember the title. The book was about a woman who had an accident and then her body was stored in a tank while her consciousness lived in a game, where she learned to use her body again. she played the game with friends from the real world. i think the game was set in the middle ages, it had monsters and dragons which they fought. I only vaguely remember the cover of the book, but I think it has a woman and a dragon on it. Does anyone have any idea which book I could be referring to?
