Heaven's reach

The fugitive settlers of Jijo, both human and alien, face a final confrontation with a brutal enemy that has pursued them for centuries. Their only hope lies with the Earthship Streaker, crewed by uplifted dolphins and an untested human commander. Streaker carries ancient artifacts that could reveal the origins of intelligent life in the Galaxies, potentially averting an age of terrifying changes that threatens Galactic civilization. The survival of sentient life rests on the improbable dream that age-old antagonists can recognize the unity of all consciousness.
