Bowl of Heaven - Gregory Benford

n nSF masters Gregory Benford and Larry Niven spin a tale of alien encounters and strange technologies on an epic scale n nIn Bowl of Heaven, the first collaboration by science fiction authors Larry Niven (Ringworld) and Gregory Benford (Timescape), the limits of wonder are redrawn once again as a human expedition to another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure half-englobing a star, with a habitable area equivalent to many millions of Earths...and it's on a direct path heading for the same system as the human ship. n nA landing party is sent to investigate the Bowl, but when the explorers are separated--one group captured by the gigantic structure's alien inhabitants, the other pursued across its strange and dangerous landscape--the mystery of the Bowl's origins and purpose propel the human voyagers toward discoveries that will transform their understanding of their place in the universe.n
