Suggest me a Star Wars book in which Revan has a (big) part

I don’t have much money to gift sth big to my bf this Christmas, so I’m gonna gift a book.

I got him Star Wars One Republic Revan for his birthday and I hate Star Wars and I have no idea which book I should get next.

He said he wanted that book bc he likes Revan.

I’m open to other suggestions.
