'The legendary Ceph have been in stasis for forty two millennia. In a century, they’ll wake. History remembers them as an unstoppable force, employing a mysterious power to decimate sentient life on the planets they attacked.
'Jaya’s first mission as a new Shaman Justice is to lead an expedition into the perilous Ceph Sector. If she can learn how to contain or fight the sha-energy-using Ceph, Galaxy Proper might let them live. If not, destroying the Ceph’s home world, with all of them on it, will prevent the Ceph from ever waking.
'Jaya will do anything to avoid the annihilation of an entire sentient species. But she has no idea what her compassionate instincts will cost her. She has a century in which to save the Ceph—unless they wake early.'
