Conjuring of Assassins (Chimera, Book 2)

Romy and her three partners in crime―a sword master, a silversmith, and her thieving brother―have embraced their roles as the Shadow Lord's agents, using their forbidden magic to accomplish tasks his other spies cannot. Now, the Shadow Lord needs them to infiltrate the home of the Mercediaran Ambassador and prevent him from obtaining information that would lead to all-out war with Cantagna's most dangerous enemy. To succeed, they will have to resurrect long-buried secrets, partner with old enemies, and once again rely on the very magics that could get them sentenced to death.
