Six of Crows is a fantasy novel written by the American author Leigh Bardugo and published by Henry Holt and Co. in 2015.[1][2] The story follows a thieving crew and is primarily set in the city of Ketterdam, which is loosely inspired by Dutch Republic–era Amsterdam.[3][4] The plot is told from third-person viewpoints of five (seven if the opening and closing chapters are considered) different characters. The novel is the first of a duology, completed in Crooked Kingdom (2016). The series is part of Bardugo's Grishaverse.[5][6] Nina's storyline continues in the King of Scars duology: King of Scars (2019) and Rule of Wolves (2021), with the other Crows making brief cameos in the latter. They are also featured in the Netflix television series Shadow and Bone (2021–2023), the series' first season giving them an original storyline.
