Two neighbors sit nearly level at the top of Tor Books' similarity graph — J.K. Rowling at 0.81 and Writer's Digest at 0.81 — and they represent genuinely different audience neighborhoods: one is an author, the other a craft-and-industry magazine. That split is the defining structural feature here.
The shape is two-peak, meaning the audience doesn't consolidate around a single type of entity but bridges two clusters. The first cluster is authors: J.K. Rowling (0.81), Stephen Fry (0.79), and Neil Gaiman (0.79) are all classified as Authors, and their presence suggests an audience that follows individual literary figures closely. The second cluster is writing-world infrastructure: Writer's Digest (0.81) and Goodreads (0.76) point toward readers who engage with the craft and community of reading and writing as a practice, not just a fandom.
Beyond those two peaks, the top 10 fills in with actors — Allison Janney (0.80), George Takei (0.76) — and Chris Hadfield (0.77), a Professional. The Jim Henson Company (0.76), an Entertainment brand, and Idina Menzel (0.76), a musician, round out the set. No other Book Publishers appear in the top 10; the audience's shape is defined almost entirely by cross-kind neighbors — authors, actors, and media channels — rather than by Tor's own publisher peers.
The overall picture is an audience that sits at the intersection of literary fandom and writing culture, with a secondary pull toward broadly literate, culturally engaged entertainment.
