DreamHaven Books & Comics, established 1977 by Greg Ketter, is a Minneapolis, Minnesota independent bookstore specializing in science fiction, fantasy and horror.

[4] In the store's second year of operation, Ketter moved his storefront to downtown Minneapolis, renaming it "The Compleat Enchanter", a reference to a collection of stories by L.Sprague de Camp.

Ketter and his partner Lisa Freitag, friendly with a wide variety of authors, artists, publishers, and convention-organizers, invited numerous high-profile names in the science fiction and fantasy genres to Minneapolis for these events, including Poul Anderson, Clive Barker, Robert Bloch, Harlan Ellison, Joe Haldeman, Spider Robinson, F. Paul Wilson, Gene Wolfe and Roger Zelazny.

[4] The store's success freed Ketter to hire full-time staff, and to travel to comics shows, or to attend sf & f or horror conventions and make personal invitations to the writers he wanted to bring to the Twin Cities.

The convivial DreamHaven model, combined with the diversity of material in the store's stock, was, in these early years, an inspiration to other entrepreneurs within the sf & f community.

"[7] By the close of the 1980s, book retailers had begun to move away from their "shaggy roots," where "a typical owner's financial goal was to be able to own a decent used car" to something "more professional.

Gaiman's first event at DreamHaven Books would be his joint appearance with fellow Englishman Terry Pratchett on the release of Good Omens (1990, aired as a popular TV series in 2019).

Until the upheaval of civic disorder receded, Ketter, along with family and friends, slept at the store to prevent DreamHaven from sharing Uncle Hugo's fate.
