yeah, past the sklansky's I can't really recommend any, Phil G's books are as dumb as he is and I haven't read most of the rest. If you are interested in the HORSE games the FT tourney book is about 1/2 NLHE and the rest is mixed and was a nice intro into those games for me. Small Stakes Hold em and HPFAP are also great but limit focused and you'd probably be better off just re reading ToP and T&P.

The Poker Mindset is good if you tend to tilt or even just be overly
depressed by a bad beat/session.

Positively Fifth street is interesting in stretches but is too slow imo and obv is not meant to improve your game.
