John Clute writes that Sullivan "began publishing sf with stories like "Tachyon Rag" ... "My Father's Head" ... and "The Rauncher Goes to Tinker Town" ... tales whose sophistication led to some disappointment when his first-published novels turned out to be three ties to the
V Television series, a series of exercises in easy Paranoia set in an America taken over by Aliens... The published order of Sullivan's books was, however, deceptive, as his first-written novel, ''Destiny's End
(1988), had suffered delays and modifications at the hands of the publisher to which it had first been contracted. The book proved to be a complexly moody depiction of humanity at the end of its tether in an array of Dying-Earth venues, as Secret Masters from the stars with quasimagical Technologies manipulate the course of events. Other sf of interest included The Parasite War
(1989), which garishly intensifies the premises of V
with a few scattered humans engaged in guerrilla warfare against the Aliens who have nearly destroyed the planet; The Martian Viking
(1991), in which a prisoner escapes from Mars and roams space and time with stern but rowdy Vikings; and Lords of Creation'' (1992), which combines palaeontological fantasy including dinosaur eggs and another alien Invasion." Science fiction scholar Fiona Kelleghan has written that Sullivan "often turn[s] to classical history and mythology to dramatize his concerns about contemporary American culture - although the historical settings suggest a
Santayana-esque view of our so-called post-historical era. ... Sullivan cares deeply about his characters. His books are viciously funny in a deadpan way..."
The Locus Index to Science Fiction: 1984–1998 described ''Destiny's End'' as a "transcendental, philosophical space opera." Christine Hawkins, in her online
Mars in Science Fiction Bibliography, described
The Martian Viking as "reminiscent of
Philip K. Dick". The reviewer of the Schlock Value review website said, in a mostly positive review of the same novel: It's a well-established fact that the two coolest things ever are
Vikings and
Mars, and now, thanks to Tim Sullivan, we get both of them in one convenient package. How could this book be anything but great? Unfortunately,
The Martian Viking deals a lot less with Vikings than we were promised, although Mars does feature quite prominently, and as far as crapsack future societies go, the book does present us with a pretty interesting one... The world we are presented with is a fairly interesting form of
dystopia... All-in-all,
The Martian Viking was a pretty fun read... Tim Sullivan managed to set up a really interesting future world. ''Raymond's Reviews
said of The Martian Viking'', "it had some moments of warped originality that were hard to forget."
Robert Silverberg, who purchased Sullivan's early story "The Rauncher Goes to Tinker Town" for his
New Dimensions series of science fiction anthologies, called it "vivid and energetic". Sullivan's short story "Under Glass" has received much attention.
Lois Tilton wrote, "This is a story of friendship and the duty we owe to our friends." Reviewer Sandra Scholes said in a review of the November/December 2011
The Magazine of Fantasy & Science Fiction that the issue "gets straight to it with a tasty novelette, "Under Glass" by Tim Sullivan; who sees everything with a writer's vision of the future we have never known yet or at least until it is too late." Sam Tomaino, another reviewer of the same issue of
F&SF, urgently wrote, "The fiction in the issue starts with "Under Glass" by Tim Sullivan... This was an imaginative, moving, wonderful novelette and one that will be on my
Hugo short list for next year." Sullivan's 2013 story "The Nambu Egg" received praise from the SF CrowsNest website: "'The Nambu Egg' by Tim Sullivan is definitely Science Fiction. It is set in the distant future when the Tachtrans Authority can beam people to a distant planet,
Cet Four in this case. Adam Naraya has returned to Earth because he has a Nambu egg to sell to the head of a rich corporation, one Mr. Genzler. To tell more of the plot would be to ruin it for it's the kind of tale where things are slowly revealed. Rest assured that the length of this paragraph does not reflect the very high esteem I have for the story." Colleen Chen, writing a review for
Tangent magazine of "Through Mud One Picks a Way", said, "Sullivan revisits a space and time he's written about before — a future in which main characters hail from Cet 4, a heavy-gravity planet tough to live on but with abundant natural resources. In this story, taking place on Earth, Uxanna Venz has been hired by a fellow named Hob to communicate with three Cetians whom he has illegally obtained and wants to use for his own benefit. The Cetians are amorphous, clammy creatures whose home is the bogs of Cet 4, and they communicate with Uxanna by touching her with squidlike tentacles they can form at will. Uxanna earns their trust at the same time as she feels guilty for doing so. They've been so abused on their home planet by humans encroaching on their territory, and she knows Hob can't have good intentions for them. There's more twists to the story, though, as Uxanna learns the truth about their appearance on Earth, and then unveils her own surprises as she tries to do what's best for the Cetians at the same time as earning her money. I've read one other story by Sullivan that takes place in this universe. I liked this one more — although maybe it's just that the author's particular style, which seems to develop both plot and characters mainly through dialogue, is growing on me. But this story has enough action to keep the story moving despite the lengthy dialogues, and thus it translates into a visual piece that I felt I could watch like a movie in my own head. The characters were likable, the world-building strong, and although the ending is left somewhat unresolved, it stops at a point which promises later continuation." Eamonn Murphy, writing for the
SF Crowsnest, agreed: "Through Mud One Picks A Way" by Tim Sullivan ... is genuine Science Fiction about three aliens from Cet Four who have been transported to Earth by a businessman for purposes unknown. He has hired Uxanna Venz to communicate with them by touch telepathy, which they do well. She worked on their home planet and is an expert on the species. A nice parable about colonialism with a couple of decent twists to keep you surprised. It was mostly written in dialogue with very little narration, but Sullivan managed to get all the background information across anyway. A neat trick." == References ==
