Sun Wolf

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)
