The book of dragon

"In Dragon, Vlad finds himself in the last place any self-respecting assassin wants to be: the army. Worse, he's in the middle of an apocalyptic battle between two sorcerous armies, and everyone expects him to perform a role that they won't explain."

"In Issola, Vlad's aristocratic friends Morrolan and Aliera have disappeared. According to the eldritch (but affable) Sethra Lavode, they may be in the hands of the Jenoine--the mysterious beings who made the world of the Dragaeran Empire and its surroundings."--P. [4] of cover.
