Treason Keep — Jennifer Fallon

R'shiel stands on the brink of death. Her only hope is the healing powers of the Harshini--magical beings long-thought extinct.
Even they will be hard-pressed to save the Demon Child of prophecy...

On Medalon's northern border, Tarja and the Defenders are far too few to stand against the invaders from Karien, even with the new fortifications built onto Treason Keep. The only thing that can save them is an alliance with Hythria, with whom Medalon has been skirmishing for generations. But can Tarja trust Damin Wolflblade, warlord and heir to the throne of Hytrhia, with whom Tarja has personally crossed blades upon the field of battle?

Meanwhile, King Hablet of Fardohnya weds his eldest daughter, the stunningly beautiful but shrewish Princess Adrina, to the Karien Heir. Hablet hopes to place his grandchild on the Karien throne. But the wayward and rebellious Adrina has her own plans, and the fate of three nations dangle upon her insolent whim.
