I recommended this on a recent episode of WSIRN: episode 196 with Anudeep Reddy as a gateway fantasy, a fantasy novel for people who don't like fantasy. I loved this so much that we're reading this in February with the Modern Mrs. Darcy Book Club. This is a literary mystery, a book about books, coming-of-age story, a tale of adventure and suspense and revenge, and tattoo artistry is a main theme. This was creative and inventive and lots of fun. Also note, this was great on audio.
