Are there any good books (preferably fictional, but I won't split hairs) that feature samurai and/or shinobi prominently? Pic related has me wanting to read something in that vein

I know someone asked this question in the previous thread, and I took note of the suggestions that caught my interest, but I'd appreciate any other good recs on books/series that are about samurai and/or shinobi. Like that anon, Ghost of Tsushima has rekindled that particular area of interest, so anything of that nature would more than suffice
