How this plan is calculated
The plan comes from the pages and ratings of each volume: we split the series into stages of about three weeks’ reading, size each break to the stage before it, and read the chance of finishing from how many readers rate the last volume compared with the first. How we work out the plan →
Every volume in order
No volume in this series has enough ratings to enter a ranking yet, so the list carries no scores — the order and the volumes are still complete.
