Plague of Locusts — Daniel G. Keohane

In the late twenty-second century, Father Gendrick Hellerton begins his new role as priest of the Toojay settlement - an earthlike planet soon to be the next of many New Earths to come with the discovery of the Holes. Circling Toojay, a swarm of Locusts follows the sunset with an insatiable appetite for anything unwary enough to be outside after dark. Gendrick's predecessor, Mother Doneele, is going home, taking with her a dark secret and darker mind. Her final month on Toojay may prove more dangerous than anything from the skies. Peyton Kay is living her dream, having discovered not only the newest Hole leading to the newest Eden for humanity, but something far more wondrous: a derelict alien ship hovering on the other side. However, she and the crew of the Washington soon learn that this vessel is far from lifeless.
