Arcady lies on the Borders, with their ancient ruins and wondrous artifacts.  But they can be perilous: those who venture too close risk disappearing forever into the Absences, voids where the fabric of reality unravels.  When Solomon Hawken is summoned home to Arcady, the Borders have again breached his family’s estate and his niece has vanished into nothingness.  With the girl’s father maddened by grief and drink, and his other brother locked into a brutal civil war, Solomon must turn to a magic he can scarcely control to save his family – and perhaps his entire world.
