Writers of the novels had to obtain approval from Paramount Pictures or CBS Consumer Products to ensure that they followed the canon established for the television series.

Ten novels are set between the show's first and third season, and feature the Charmed Ones – Prue, Piper, and Phoebe Halliwell – as the most powerful witches of all time.

[6][7] According to Paul Ruditis, authors of Charmed novels and comics must maintain "the rules for playing in that universe" and "the studio still has to approve the direction we take" as writers.

Following these regulations, authors are given creative license but strictly "couldn't go and rewrite history, killing off established characters or suddenly creating romantic pairings that we'd never see on the show".

While Michaels had first appeared in the season four episode "Lost and Bound", Ruditis had also portrayed Tyler in the novel The Brewing Storm (2004), and Shand wanted to avoid inconsistencies or "retreading".
