Sun Wolf

Adult; Sci-Fi/Fantasy/Horror; (Market)

Year 2218. Still haunted by his encounter on Silvanus, Aiden Macallan commands the Sun Wolf on an impossible mission only he can accomplish—saving the human race from certain annihilation. After fifty years of enabling human expansion into Bound Space, the enigmatic voidoids are starting to shut down. No one knows why, or who’s behind it, but one thing is certain: if the voidoids disappear, not only is humanity locked out of Bound Space forever, but it will unleash a cosmological catastrophe of runaway dark energy tearing our universe apart—from atoms to stars. It will happen soon and happen fast unless Aiden and his hand-picked crew can stop it. And only if they can outrun an unseen enemy trying to kill them every step of the way. Now alone in a race against time and dark malevolent forces, the Sun Wolf is humanity’s last hope for survival.
Reviews
The second installment in Jeffrey’s Space Unbound series (after Through a Forest of Stars) follows the crew of the Sun Wolf, a high-tech Science and Survey vessel, on a journey to save the universe. When a series of government ships mysteriously vanish, and the solar system’s transportation portals (voidoids) are attacked, Commander Aiden Macallan and his team are recruited to track down the perpetrators. But what starts as a straightforward mission becomes increasingly complex, when Aiden discovers that the voidoids themselves may be sentient—and responsible for the existence of the universe itself. With the help of Maryam Ebadi, codirector of the advanced research center the Cauldron, the crew must travel outside the realm of Bound Space to track down Elgin Woo, a missing scientist with the knowledge to stop the carnage.

While the novel’s opening promises elements of mystery (Aiden’s pompous military advisor Colonel Aminu warns him not to trust anybody, even his own crew), the rest of the book is an epic space adventure written in the hard SF mode. The plot operates on a grand scale, featuring interplanetary jumping, rogue space pirates, and warring government factions. But, like its predecessor, Sun Wolf really shines on the micro level. Aiden is a likeable, honorable protagonist who commands a diverse crew of scrappy, well-intentioned individuals. With a team of nine (and counting), not everyone gets a chance to develop, but the well-crafted character dynamics add a personal touch to the wide-ranging storyline.

Actions, weapons, and scientific concepts are explained in-depth throughout, and the plot often feels secondary to the workings of the universe itself. It is not enough to have a ship travel at 92 percent light speed—the mechanisms by which it does so are explained and re-explained. The exposition can sometimes bog down the narrative, but Jeffrey gives lovers of the genre interesting perspectives on his concepts. Adventure fans and tech aficionados alike will appreciate this cosmic escapade.

Takeaway: This detailed space opera with a touch of mystery will appeal to those interested in the science of interplanetary adventure.

Great for fans of: Peter Watts’s Blindsight, Robert Charles Wilson’s Spin.

Quick thinking, scientific acumen, and plenty of guts punctuate Jeffrey’s fast-paced second Space Unbound adventure (after Through a Forest of Stars). Someone or something is sabotaging the voidoids, portals through which ships can jump to other stars within a 36.3–light-year radius of Sol and without which the flow of space travel is disrupted. The United Earth Domain promotes scientist Aiden Macallan to captain the maiden voyage of the advanced science ship Sun Wolf to investigate. The most likely saboteur is Green War, a violent Earth isolationist group that wants to end off-world colonization, but another clue is an unidentified ship spotted near a disabled voidoid. Eminent scientist Dr. Elgin Woo, famous for hypothesizing that the voidoids may be necessary for the functioning of the universe, could help, but he has gone missing. Instead, Maryam Ebadi, Woo’s colleague on Luna Station, joins Sun Wolf on its dangerous mission. Though the prose is sometimes jargon-heavy, Jeffrey’s obvious passion for hard science shines through his immersive worldbuilding, which incorporates a diverse cast, espionage, quantum physics, and epic space battles. This well-plotted sci-fi thriller recaptures the feel of the first book and is sure to delight fans. (Self-published)
K.C. Finn for Readers' Favorite

“Author David C. Jeffrey delivers a highly captivating science fiction story that follows commander Aiden Macallan as he endeavors to save humanity from destruction. Jeffrey does a wonderful job of creating multifaceted characters . . . the scientific information given was thought-provoking and believable, and it got me thinking about the ideas explored in the novel in more depth. Sun Wolf is an exciting and imaginative science fiction novel with a twist of mystery that will keep you engaged and inspired with the universe, the story, and the characters.” 

Kirkus Reviews

“Jeffrey’s yarn is a dandy cosmic mystery conceived on the vast scale of an Arthur C. Clarke or Olaf Stapledon epic . . . there’s a gallery of well-drawn, diverse characters that may pleasantly remind readers of Star Trek; a memorably sinister cabal of villains; and even a smattering of romance. There’s also no shortage of imaginative perils along the way. A fine spacefaring adventure story on a macroscopic scale.” 

Pikasho Deka for Readers’ Favorite

Five Stars. “A pulsating page-turner that explores new mysteries and newer horizons, Sun Wolf is an entertaining sequel that holds its own when compared with its much-praised predecessor. Author David Jeffrey introduces a couple of fresh faces into his epic sci-fi saga. He also provides in-depth backstories to his older characters and develops them further. Overall, Sun Wolf was a blast to read. I think it is a must-read for sci-fi fans.”
