First print with coplete number line. Tight, clean, flat, square and crisp book with marginal toning. In a realm beset by natural disasters, only the magical abilities of the bonded Pairs--Source and Shield--make the land habitable and keep the citizenry safe. The ties that bind them are far beyond the relationships between lovers or kin--and last their entire lives. Whether they like it or not. The Empress wants to locate the descendants of her exiled sister. No magically-bonded Pair is more ill-suited for the job than long-suffering Shield Lee Mallorough and her all-too-charming Source Shintaro Karish. Yet it's a mission they can't refuse.
