Similar books on every book page

Every book page now has a "Similar books" shelf — titles that people who read this one tend to reach for next. There's always a handful to browse, so it's an easy way to line up your next read without leaving the page.

A book never sits on its own — it's part of a web of what readers move through together. Surfacing that directly on the page turns "I finished this, now what?" into a single glance.
