This question already has an answer here:
I read a series of books 20+ years ago in which the players of an RPG were transported to inhabit their characters while in the campaign they were playing.
There was a paraplegic or quadriplegic who was a mighty dwarf fighter, an abused teen girl who was a healer, a wizard named Andrea, a thief who only had one hand and was killed off early.
The handicapped guy who was the dwarf and the healer liked being in the player's universe because they had abilities they otherwise could not have.
I remember the series was at least 5 books geared toward the Young Adult reader.
