Rachel Caine rewrites history, creating a dangerous world where the Great Library of Alexandria has survived the test of time. In 48 AD, a fire set by the troops of Julius Caesar destroyed much of the Great Library of Alexandria. It was the first of several disasters that resulted in the destruction of the accumulated knowledge of the ancient world. But what if the fire had been stopped? What would the Library have become? Fast forward: the Great Library is now a separate country, protected by its own standing army. It has grown into a vast power, with unquestioned and unrivalled supremacy. Jess Brightwell, seventeen and very smart, with a gift for mechanical engineering, has been sent into the Great Library as a spy for his criminal family. Magical spells and riots abound in this epic new YA series.
