Maybe try a chessable course. I think they might have some on the Smith morra and other anti Sicilians
what is the best book for the smith morra gambit?

Mayhem in the Morra! by Marc Esserman is a book I've seen recommended by people like Eric Rosen and Danya Naroditsky as an in-depth and comprehensive look on the Smith-Morra. It's something I wanted to pick up at some point myself, and it does have a chessable course based on it too.

The Modern Morra Gambit , 2nd Ed., by Hannes Langrock

i have played D4 this whole time and i want to transition to e4 but, i want to have a weapon against the secilian (the smith morra) and i was wondering what book i should read. I own Winning with the smith morra gambit by graham burgess and i own mayhem in the morra. If you have any other books i should read please suggest them.
Be warned that the Smith Morra leaves black better if black knows how to play it. Some think it's a forced win for black but the reality is that white has to fight hard for a draw and in doing so, might win.
I learned it from Smith's book years ago but the losing lines for white weren't discovered.
Looking forward to how you would improve Black's play in the game shared at https://www.chess.com/forum/view/general/what-is-the-best-book-for-the-smith-morra-gambit#comment-71400623
