A #1 New York Times bestseller "A rip-roaring adventure merged with satisfying romance." -- Entertainment Weekly " A] swashbuckling launch to the Eldest Curses series." -- Publishers Weekly From #1 New York Times and USA TODAY bestseller Cassandra Clare and award-winner Wesley Chu comes the first book in a new series full of "swoon-worthy romance and] abundant action" ( Publishers Weekly ). The Red Scrolls of Magic is a Shadowhunters novel. All Magnus Bane wanted was a vacation--a lavish trip across Europe with Alec Lightwood, the Shadowhunter who against all odds is finally his boyfriend. But as soon as the pair settles in Paris, an old friend arrives with news about a demon-worshipping cult called the Crimson Hand that is bent on causing chaos around the world. A cult that was apparently founded by Magnus himself. Years ago. As a joke. Now Magnus and Alec must race across Europe to track down the Crimson Hand before the cult can cause any more damage. Demons are now dogging their every step, and it is becoming harder to tell friend from foe. As their quest for answers becomes increasingly dire, Magnus and Alec will have to trust each other more than ever--even if it means revealing the secrets they've both been keeping.
