Jhereg is a fantasy novel by American writer Steven Brust, part of his Vlad Taltos series, originally published in 1983 by Ace Books.

Vlad Taltos, a mobster and assassin in the magical metropolis of Adrilankha, is given the largest contract of his career, but the job is even more complicated than he expects.

Despite being an Easterner in the Dragaeran city of Adrilankha, Vlad is a minor boss in the criminal activities of the Jhereg Organization.

One day he is approached by the Demon, an extremely powerful member of the Organization's ruling Council, and offered an assassination job with a staggeringly large reward.

Sethra, the oldest and wisest of the group, agrees with Aliera's position, but feels that they must still respect Morrolan's wishes and find a way that will not violate his honor.

Vlad foils this solution by breaking the enchantment preventing Morrolan's resurrection and has his friend brought back to life.

Mellar is a half-breed—a mix of Dragon, Jhereg and Dzur—and intends, through his death, to get his revenge on all his parent Houses by causing two to erupt into war and leaking information that would forever shame the third.

Mellar, believing his plan is ruined, flees Castle Black to avoid a purposeless death at the hands of the Jhereg.

The House is named after the jhereg, small, flying dragon-like reptiles which possess a poisonous bite and are scavengers that primarily feed on teckla, and symbolizes greed and opportunism.
