"A novel that was anything less than stellar would be an especially disappointing follow-up to the brilliant Noumenon, but Lostetter has achieved that and much more. [...] Sci-fi action and adventure held together by universally human themes; this is the genre at its very best." -- Kirkus Reviews (starred review)

"The ambitious and effective sequel to Noumenon [...] Lostetter remains at the forefront of innovation in hard science fiction." -- Publishers Weekly (starred review)

"Lostetter delivers another feast for fans of hard science fiction." -- Booklist

"A tight, compelling sequel [...] Lostetter's characters persevere and evolve, creating a compelling portrait that feels, at its heart, ultimately both human and galactic in scope." -- Strang Horizons

"Travel to the remotest reaches of deep space in this wondrous follow-up to the acclaimed Noumenon--a tale of exploration, adventure, science, and humanity with the sweep and intelligence of the works of Arthur C. Clarke, Neal Stephenson, and Octavia Butler." -- Open Book Society

"Noumenon Infinity by Marina J. Lostetter is an excellent space opera focused on beautiful character details and grand ideas on the biggest stage possible. Highly recommended." -- Primmlife
