The cover blurb:
Valdemar- the once-peaceful kingdom protected by the magic of its Herald Mages- is now besieged on all fronts. The king lies near death, the neighboring land of Karse wages a relentless war against Valdemar, and the forces led by a master of dark forbidden magic are massing to stroke the final devastating blow against the kingdom.
And Vanyel, the most powerful Herald-Mage Valdemar has ever known, has become the primary target of the evil which is reaching out to poison all the land. With all his fellow mages slain, Vanyel alone remains to defend his people against the dark master's army. Yet a dream vision has revealed to Vanyel the fate which awaits should he and his Companion Yfandes take up the dark master's challenge. And if either Vanyel or Yfandes falters, the dream will become a horrifying reality in which both Valdemar and its last Herald-Mage must pay the ultimate price....
One of my favorite books by Mercedes Lackey. I should note before I start raving too much that this is the third book in her Last Herald-Mage series, following on Magic's Pawn and Magic's Promise.
I don't often end up in tears during or after reading a book, but Magic's Price is definitely an exception to that rule. There have been several times I've had tears running down my face at the ending of this one. Of course, at other points in this series, Mercedes Lackey's had me almost rolling on the floor in laughter too, so I guess it balances out. Especially as some of her other books have had the same effect on me - particularly Brightly Burning.
