The Court of Owls is a brilliant story that was developed by Scott Snyder, Greg Capullo and Jonathan Glapion. The story is based on the secret society that has been in existence and operating from the shadows since colonial times. They recruit people and transform them into assassins which are better known as Talons.
The book is now available as an adult coloring book which you can purchase from here and if coloring is not your thing, then the book would be a great addition to your DC collection!
