The White Rose and the Black City - Stephen Miller - Bog

There aren't many career opportunities in the city of Leifsburg for an exiled princess, but Theresa Kuypens has found her niche solving the upper crust's little social difficulties. When a family financial crisis leads her to take on a more underhanded piece of work, Theresa's uneventful life quickly gets turned sideways. With her client dead and a seemingly superhuman killer on her trail, she finds herself on the run along with Petra Ivanova, premier cat burglar and Theresa's best friend, and Vincent Hendriks, a former member of Theresa's royal guard with a few enemies of his own. The three of them soon find themselves caught in a deadly struggle between a megalomaniacal wizard bent on remaking the world and a band of cultists who simply want to destroy it. Saving the world will take every trick they can dream up. Surviving to tell the tale will take a miracle or two.
