K'reeth and her sister, K'rin, were named for the moonbirds—sister raptor birds who share parenting duties, one the nurturer, the other the hunter and defender. Orphaned by catastrophe and adopted by the High Mistrada of the T'bredi scholars, they're teachers entrusted with all the gathered wisdom of the Ayanlak.

Their bond of sisterhood is tested when K'reeth falls in love with the Wind Walker Talon. The relationship is further strained when the new peace with the Colonist invaders includes a promise to send home all the children who have been rescued by and raised among the Ayanlak—and K'reeth is the first.

Her forced journey to be reunited with a family she doesn't even remember eventually takes both sisters across the continent and into the nest of political intrigue and contention that may tear their world apart—on the very brink of peace and the fulfillment of ancient prophecy.
