Ryk E. Spoor

Publishers Weekly describes Spoor's 2017 novel, Princess Holy Aura, as "Spoor’s affable horror fantasy [in which] a 35-year-old man must transform into a 14-year-old girl to save the world from a Lovecraftian menace." The same reviewer also wrote that "The Lovecraftian abominations are sufficiently over-the-top and the fight scenes are lively, but awkward dialogue and lots of exposition bog down the already overstuffed narrative." A reviewer for PopCultHQ found the book "hilariously enjoyable and had trouble putting it down."

Reviewers for Flint and Spoor's 2015 book Castaway Planet were less favorable. The reviewer for Rosboch Book Reviews wrote that although the reviewer mildly enjoyed the struggles of the Kimei family, they "found the writing verging wildly into corny far too often" and thought that the "story is predictable and bland", unlike the previous books in the series. The reviewer for Koeur's Book Reviews wrote that the "novel went from really good to really bad, really fast. Almost like two different authors wrote separate halves."

In reviewing the 2013 co-authored novel Portal, the reviewer for Astro Guyz wrote that "Portal is hard science fiction in the tradition of Ben Bova, Hal Clement and Arthur C. Clarke."

The 2010 co-authored novel Threshold reached number 11 on the Wall Street Journal Best-Selling Books list for Hardcover Science Fiction for a week in June 2010. The book also reached number 9 on Publishers Weekly's Sci-Fi Bestseller List for a week in June 2012. A reviewer for Publishers Weekly wrote "fast-paced sci-fi espionage thriller [that] is light in tone and hard on science and a fine choice for any collection".

In reviewing the 2006 co-authored novel Boundary, the reviewer for the publication SFRevu wrote that "It's refreshing to have a book with soldiers, scientists, and secret agents, all of whom, even when having differing orders, still find ways to actually work together for the common good." The reviewer also wrote that the authors introduces a lot of technical wiz-gimmickry in a way that "it's done smoothly enough that you don't feel like you're being given a lecture". The reviewer for SFFWorld wrote that he "thoroughly enjoyed Boundary" and "found it to be a quick and easy read, one where I was continuously kept interested on what would come next, and where it would lead from there." The reviewer also wrote that "Flint and Spoor have created a memorable cast of characters and have injected a real sense of wonder into the narrative".

A reviewer for the Shiny Book Review called Spoor's first published work "fun, fast read about things that go bump in the night" and "a fine debut novel that does just about everything right".
