Trevanian And his books

Anyone liked trevanian? And his works like shibumi, katya's summer Tryna see how popular he is(i absolutely love em) Shibumi was really good because this mindset / concept of Shuibumis and Shibasus is really interesting and THOSE can be lifegoals. And it makes person inrerested in "go" its japanese chess and thats why i started go and liking it so far;) Also book is thrilling you with escaping death situations and its plot is top tier! Makes me wanna try mountain climbing, cause main character Nicholai Hel is expert at it and finds it a relaxing hobby;) Also i saw that trevanian really likes bask culture? I noticed parts of it in most of his books. Any comments about him and about Shibumi/other books of him? Thanks
