Notes: Data from Amazon UK, Kobo (GB) and publisher's site as of 2025-11-04; updated as of 2025-11-11. Print length of 813 pages listed by Amazon UK. Price is RRP as listed at publisher's site; price at Kobo (GB): £5.99. This Reddit post indicates an originally solicited publication date of 2024-09-12. As of early November 2025 it was listed with a publication date of 2025-11-06, however as of 2025-11-11, Amazon UK states that it is "Currently unavailable", and Kobo (GB) returns an error for the URL it was previously at. This Twitter post indicates that Amazon cancelled preorders on that scheduled day of publication. The publisher's website subsequently listed a publication date of 5th February 2026, and the book was available on this date. The product listing metadata has the authors as Sterling E. Lanier and Lucy Andrews Cummin, but the cover image only shows Sterling Lanier (no middle initial). However the title page (as visible via Amazon's preview states): The Concluson of Sterling E. Lanier's / Hiero's Journey HIERO's ANSWER by / Lucy Andrews Cummin The title page also has the "VG" Gollancz logo rather than the "G" Gateway logo shown on the cover.
