This square design is centered on two lines of head-and shoulders portraits of the Orangeboro Pack members. Above the pictures it says, “MEET THE ORANGEBORO PACK.” Each row of five has the dogs’ names centered under their portraits. Upper row, L-R: RAZOR (black & tan), ELLE (russet & white), CRYSTAL (white), PETUNIA (yellow-gold), and CINNAMON (russet). Lower row, L-R: SCOUT (chocolate brown), VICTOR (tricolor black, russet & white), TUXEDO (black & white), SHADY (black sable with brown undercoat, and REX (black).

Meet the XK9s in Jan S. Gephardt ‘s books about a pack of uplifted police dogs. They live in a science fictional future on a megastructure called Rana Habitat Space Station. I’ve written several blog posts about space stations, as well as specific things about the political structure, culture, and other aspects of Rana.

The XK9 Project designed their dogs, called “XK9s,” to be state-of-the-art forensic olfaction sensors. They have a verbal interface, meant for handler convenience. And they’re verbal, all right. But they’ve transcended being mere talking equipment. Anybody who’s ever had a really smart dog will have predicted that.

Are you ready to meet the XK9s?

This square image has a variegated brown background and a fairly strong yellow oval shape in the center. In front of that are an ebook and slender paperback of “The Other Side of Fear” by Jan S. Gephardt. Cover art shows a woman’s shoulder and the side of her face in the foreground. Viewers look as if from behind her toward a bonfire and an enormous wolflike dog in the middle ground. Behind the dog and the fire a group of bundled-up humans in coats and jackets look on, backed by a forest. Across the top the words say, “’Highly imaginative science fiction,’ – Robin Wayne Bailey, Author of the ‘Brothers of the Dragon’ Series.” Below that, “The Other Side of Fear, A novella about the XK9s. By Jan S. Gephardt.” Cover art © 2020 by Lucy A. Synk.

The Other Side of Fear

This prequel novella happens before the action in the XK9 “Bones” Trilogy. In it we follow one officer, Pamela Gómez. She travels to Chayko, the planet shown in the background of the video above, as an XK9 partner-candidate. The Orangeboro Police Department has contracted to buy 10 XK9s. Pam is one of 30 officers who hope to be Chosen by a future XK9 partner.

The XK9 “Bones” Trilogy

The XK9 “Bones” Trilogy tells the exploits of XK9 Rex Dieter-Nell and his XK9 Packmates, once they’ve arrived on Rana Station. Rex is an enormous, bio-engineered dog who is way too smart for his own good. Or for the peace of mind of many of the humans he meets. Once a human shows him how to “leverage his influence for a better outcome,” he’s on his way to chart a new path. No matter what.

Orangeboro PD decided that XK9s would be a great a tech-upgrade. What they really are is more than anyone–especially their creators at the XK9 Project–ever intended them to be. Or hoped their new owners would figure out. But Chief Klein is an honorable man. And Rex is a determined dog. And Ranans–unlike some cultures–don’t throw people away.

On a variegated green background, we see two 3D versions of the book “Bone of Contention.” One is an ebook with a black frame. The other is a fat trade paperback. On each, the words of the cover, from top to bottom, say: “’The XK9s prove irresistible’ – Kirkus Reviews, of “What’s Bred in the Bone.” Bone of Contention. Jan S. Gephardt.” In the upper left corner among the leaves and fruits of an orange tree, a round symbol shows the series “Leaping Star-Dog” logo, with the markings “3” and “XK9s.” The cover painting shows the odd perspective inside a toroid space station’s habitat wheel, with green, terraced hills and a winding river running through the center. In the foreground, under an orange tree, is the entrance to the Orangeboro Police Department, with a golden, 7-pointed star-badge emblem on the portico. Atop and behind the emblem crouches an odd, gray being. Below, XK9s Shady, a black sable, and Rex, pure black, leap down the mosaic-textured steps in their harnesses and panniers, ready to run. Behind them their human partners, wearing police uniforms follow them at a run. Charlie is a tall Black man. Pam is a petite Latina with long dark hair. Below the two books, it says, “Cover art ©2024 by Tom Kidd.
