Not many choices available for Benoni unfortunately, but luckily they are usually pretty good . The most recent was probably the one in Quality Chess Grandmaster Repertoire series ( i think it's by Marian Petrov, who may still post on here), which i think recieved quite favourable reviews.

Palliser has written a book or two on the benoni. First one was aimed at the weaker player. The most recent one at the stronger player and didnt provide a full repertoire as it only focused on the more popular lines white may play. Still recieved favourable reviews.

John Watson's book on the benoni was good, but maybe a little dated now.

Mastering the benko and benoni. Pretty old now, but focused on the pawn structures and the relevant strategies to follow rather than the theory.
