The book was published in 2016. This book is a sequel of "Six of Crows".
The main characters try to save their friend Inej, take the grishas from Ketterdam, and make Van Eck pay for his fraud.
In this book I like that the main characters could find happiness after all problems. And most of all I remember the auction, where the main characters get revenge on Van Eck. This book has taught me not to stop no matter what.
