Jhereg (novel)
Jhereg is a fantasy novel by Steven Brust in his Vlad Taltos series, originally published in 1983 by Ace Books. Ace later republished it in 1999 as part of the three-book omnibus, The Book of Jhereg. Marvel Comics adapted the story into a graphic novel titled Steven Brust's JHEREG in 1987.
The novel is named after House Jhereg, the Great House to which Vlad Taltos belongs. The House in turn was named after jheregs, tiny dragon-like creatures native to Dragaera, one of which Vlad keeps as a familiar.
