SUN WOLF, the sequel to THROUGH A FOREST OF STARS Year 2218 Why does a man, haunted by a profoundly intimate encounter with an alien intelligence, troubled by a traumatic past, and stalked by a potentially devastating addiction accept an impossible mission to save humanity from certain annihilation? Because he is Aiden Macallan, commander of the Sun Wolf , and those afflictions make him the only person for the job. After fifty years of enabling human expansion into Bound Space, the enigmatic voidoids are beginning to shut down. No one knows why, or who’s behind it, but one thing is certain: if all the voidoids disappear, not only is humanity locked out of Bound Space forever, but it will unleash a torrent of 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. But as they set course for the Frontier in search for answers, someone is trying to stop them, attacking from the shadows at every step of the way. Someone who just might want the destruction of the voidoids to proceed. Now, in a race against time and malevolent forces, light-years from home, the Sun Wolf is humanity’s only hope for survival.

I'm looking forward to the next books in the series!" ★★★★★ "Great balance of science and story . Strong characters. Looking forward to the sequel!" " 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. " -- Kirkus 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. . . 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. . . well-crafted character dynamics add a personal touch to the wide-ranging storyline. . . This detailed space opera with a touch of mystery will appeal to those interested in the science of interplanetary adventure." - - Publishers Weekly BookLife "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." Pikasho Deka 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." -- K.C. Finn for Readers' Favorite "The second installment in David C. Jeffrey's Space Unbound saga (after 2020's Through a Forest of Stars ) continues the grand-scale science fiction narrative . . . The hard scientific speculation is consistent throughout; the central characters are deeply developed; the pacing is brisk, and the action irrepressible. . . . fans of hard science will enjoy the story." -- BlueInk Review David C. Jeffrey was born in 1947
