What do I read aftwrTrevanian’s Shibumi?

What do I read after Trevanian's Shibumi?

I absolutely loved this book.

I loved that it really gave you an in depth look at different cultures- the Japanese, Basque & American

I thought his writing was fantastic and the book was extremely immersive

The characters were colorful & contrasted eachother extremely well

There was a thread of asceticism throughout that I very much appreciated.

Also, it was extremely funny.

The philosophy in it was absolutely spot on for me.

And the plot- the espionage, violence, etc was great!

Can anyone recommend where I should go next????
