Azure Ravens

Publisher's blurb:

The Azure Ravens are a spy network operating throughout Western Europe. They serve no king, no politician, and ask for no coin. Their main goal is to hold the most powerful people in the land to account by gathering secrets and sewing intrigue. Most Ravens are trained in hand to hand combat and some known to have even dabbled in the art of assassination. They have made many enemies along the way. When a lone Raven known only as “A” goes missing while in possession of vital documents, it falls to others of their flock to avert conspiracy and intrigue.
