A gripping sci-fi thriller—and Native American First Contact story—from the New York Times bestselling author of Robopocalypse, Daniel Wilson, who is a Cherokee Nation citizen and works as a threat forecaster for NASA. Heliopause is a real place—the very outer edge of our solar system where the sun's solar winds are no longer strong enough to keep debris and intrusions from bombarding our system. It is the farthest edge of our protected boundary (it was recently crossed by Voyager), and the line beyond which space experts look for extraterrestrial presences. This is where Daniel Wilson's fascinating novel begins. Weaving together the story of Jim, a down-on-his-luck absentee father in the Osage territory of Oklahoma, and his daughter, Tawny, with those of a NASA engineer, a misfit anonymous genius who lives in military isolation analyzing a secret incoming "Pattern," and a CIA investigator tasked with tracking unexplained encounters, Heliopause explores a Native American first contact that pulls all five characters into something never before seen or imagined.
