Publication order
6 volumes1980–2011Completed
- Six volumes, one continuous story of Ayla — read in order from The Clan of the Cave Bear (1980).
- The books get longer and more descriptive as they go; if the first one carried you, the rest ask for patience.
A plan for the whole series
6 volumes, 4,432 pages, about 80 hours. At 45 min a day that is about 4 months.
Share of volume 1’s readers who reach the last volume. Chance of reaching the last volume: low
- The thickest volume runs 953 pages. One volume is one stage: a break after it, not the next volume.
- From volume 2 on, the number of ratings falls most before volume 4, “The Plains of Passage” (by 31%).
- Readers scored volume 3, “The Mammoth Hunters”, below its predecessor (7.6 after 7.9). If you slow down there, that is on the book, not on you.

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 →
