Six of Crows: A Darker Shore, Letters from Ketterdam -- Leigh Bardugo, Hardcover

From #1 New York Times bestselling author Leigh Bardugo comes a new Grishaverse short story: a mystery told through found documents and set after the events of Crooked Kingdom.

In the years since the violent upheaval caused by the auction of Kuwei Yul-Bo, the merchants of Ketterdam have been under attack. Secret businesses exposed. Ships sunk. Slavers hunted as they once hunted their victims. All the work of a mysterious sea captain and her ship, the Wraith.

Now, two investigators meet to uncover the truth behind the latest disaster: a massacre on an island off the shores of Ketterdam. Among the evidence collected is private correspondence between notorious crime boss Kaz Brekker and an anonymous sailor aboard the Wraith known only as "I."

Follow along with the lead investigator as he tries to piece together how such a disaster transpired, and explore the Grishaverse like never before with new illustrations by E.K. Belsher and in-world collectible items.
