Winter in Tandora finds the country locked in a stalemate of war, and Charlie of Windsong remains with the Heir's Army to support Prince Justinian's fight for the throne.
Loyalties and allegiances prove tenuous during times of conflict, and a sudden betrayal forces Charlie to flee for her life in the dark of night. She escapes her pursuers with the help of friendly strangers and finds refuge in a fantastical place where she is welcomed as an honored guest. But the longer she stays, the more suspicious she becomes that not all is as it seems in this magical place, and she is uncertain who she can trust. When the truth is revealed, Charlie finds that the outcome of the war rests on a decision she must make. Her choice leads her on a fast-paced adventure through the Eastern Lands where she encounters danger, subterfuge, and someone from her past.
Her journey to Shala reunited her with her father, and her father's political scheming brought her back to her home country. Now to save those she cares about, Charlie must depend on her own abilities as she takes on a task that puts her at the center of the battle for the country. On this next adventure, Charlie encounters magic beyond what she has ever seen, steps into her new role as leader of the Order of the Dagger, and takes the future of the Eastern Lands into her own hands.
