City of Dark Magic

Once a city of enormous wealth and culture, in its day Prague was home to emperors, alchemists, astronomers. When music student Sarah Weston finds herself with a summer job at Prague Castle cataloging Beethoven's manuscripts, she has no idea how dangerous her life is about to become. Prague is a threshold, Sarah is warned, and it is steeped in blood.
It's not long after Sarah arrives that things start to go wrong. Her mentor, who was working at the castle, is thought to have committed suicide. Then Sarah begins to discover cryptic notes from him; could they be warnings? Following the clues about Beethoven's 'Immortal Beloved', Sarah gets into more trouble than she could have reasonably expected. Arrests, sex and a touch of alchemy take Sarah on an exciting and occasionally dangerous trip. Along the way she catches the attention of a four-hundred-year-old dwarf, the handsome Prince Max, and a powerful U.S. senator with secrets she will do anything to hide.
City of Dark Magic could be called a rom-com paranormal suspense novel—or it could simply be called one of the most entertaining novels of the year.
