I don't think there's any other quest to receive the 1st RB book. The only quest that gives an RB book (which is unfortunately 2nd) is the Street of Heroes quest after you complete the chain of quests.
I could be wrong. In any case, the money to buy the RB book from a trusted friend shouldn't be too hard to get, assuming you go for a maximum of 10:1 ratio.
