The Impossible Contract — K.A. Doore

A young assassin embarks on “a heart-pounding adventure through an inviting, richly imagined world [in] this triumphant fantasy” (Publishers Weekly).

An assassin's reputation can mean life or death. This holds especially true for Thana Basbowen, daughter of the legendary Serpent, who rules over Ghadid's secret clan of assassins. When she's offered a top-tier contract to eliminate a foreign ambassador, Thana seizes the opportunity … only to realize she is in over her head. 

Ambassador Heru Sametket wields blasphemous powers against his enemies, and Thana isn't the only person after his life. Even the undead pursue him, leaving behind a trail of horror. Her mission leads her into the heart of a power-hungry empire, where dangers lurk around every corner. Her only ally is Mo, a determined healer set to protect Ghadid any way she can.

As further occult secrets are unleashed, however, the aftermath of this impossible contract may be more than anyone can handle.
