Shadow & Crown
by E. L. Tenenbaum
Three year after the mysterious Piper of HameLonn disappeared, Quirin stumbles upon a lost girl. He gives her shelter at the farm he works on, and, wanting no trouble, deliberately keeps his distance. As unanticipated events force them together, Quirin becomes certain that quiet Cal is hiding a very powerful secret. Worse, he suspects Cal knows that he is, too.
