This Collider article argues that true Stephen King devotees can be distinguished from casual readers by their familiarity with his lesser-known or more challenging works, beyond staples like The Shining, Carrie, Salem's Lot and IT. It presents a curated list of eight titles that require deeper knowledge of King's interconnected fictional universe, arguing that reading these books signals genuine "Constant Reader" status rather than passing familiarity with his most famous horror hits.

The piece highlights books such as Insomnia, a nearly 800-page novel described as vital to The Dark Tower series and packed with references to King's wider body of work; The Eyes of the Dragon, a fantasy novel notable for introducing the recurring villain Randall Flagg; and The Long Walk, representing the seven novels King wrote under the pseudonym Richard Bachman, including the out-of-print Rage. The article frames these picks as demanding more context or patience than King's mainstream classics, making them better suited to dedicated fans.
