Empire of exiles
(Book)

"Twenty-seven years ago, a Duke with a grudge led a ruthless coup against the empire of Semilla, killing thousands. He failed. The Duke was executed, a terrifyingly powerful sorcerer was imprisoned, and an unwilling princess disappeared. The empire moved on. Now, when Quill, an apprentice scribe, arrives in the capital city, he believes he's on a simple errand for another pompous noble: fetch ancient artifacts from the magical Imperial Archives. He's always found his apprenticeship to a lawman to be dull work. But these aren't just any artifacts - these are the instruments of revolution, the banners under which the Duke lead his coup. Just as the artifacts are unearthed, the city is shaken by a brutal murder that seems to have been caused by a weapon not seen since the days of rebellion. With Quill being the main witness to the murder, and no one in power believing his story, he must join the Archivists--a young mage, a seasoned archivist, and a disillusioned detective - to solve the truth of the attack. And what they uncover will be the key to saving the empire--or destroying it again"--,Provided by publisher.
