Book Three of the InterstellarNet Saga. Contact with other intelligent races in nearby star systems seemed to have answered the age-old question at the center of the Fermi Paradox: Where is everybody? But when Joshua Matthews lands a new job that will give him access to vast new troves of data on the subject, suddenly everything goes wrong for him. Someone is sabotaging his life. Finding out why leads in astonishing and dangerous directions. It is as if he has tugged on one thread, very gently-and caused everything humanity knows about its place in the universe to unravel, awakening the enmity of unsuspected ancient powers. InterstellarNet: Enigma incorporates the 2015 Hugo-nominated novelette, "Championship B'tok." "When people talk about good hard SF-rigorously extrapolated but still imbued with the classic sense-of-wonder-they mean the work of Edward M. Lerner, the current master of the craft. InterstellarNet: Enigma is Lerner's latest gem, and it's up to his usual excellent standards; a winner all around." -Robert J. Sawyer, Hugo Award-winning author of Red Planet Blues "Yes, this is a hard science story, and yes, it's really, really good." -Kristine Kathryn Rusch on The Matthews Conundrum (Part One of InterstellarNet: Enigma ) "Edward M. Lerner's InterstellarNet is one of the most original and well-thought-out visions of an interstellar civilization I've ever seen." -Stanley Schmidt, Author of Argonaut "A breathtakingly richly realized vision of what tomorrow's civilization may look like - and the people who inhabit it." -Ben Bova, Author of the Grand Tour series
