Twins are special; Auronar clone twins doubly so. They're grown that way. Pilot Skate Cally and Operative Merrin Cally are a flight team on the Auronar cruiser Flag of Hope. They've been in each other's heads, living each other's lives, the same feelings, differences, orders and taste buds, since they were first poured out of a vat. But after High Command sends Skate on a one-way mission investigating Federation incursions in the Dancer Cluster, Merrin faces a bleak new future on her own.
On Auron, every clone lives in a world buoyed by the constant murmur of telepathic support, gossip, and opinions. When Ariane Cally's plane crashes in the middle of a wilderness park, she finds herself cut off not only from rescue, but the voices that have sustained her all her life. Her only hope is the mysterious Aunty, the single voice she can still hear, a woman who claims to have been the second Cally ever to be born on Auron.
