Usually sequels are very picky for me, more often than not, I would pick up the first book, like it and then not be even remotely interested in the sequel (even in a duology) but this one has got to be one of the most fascinating, fast paced, plot twist after plot twist book sequel I've ever read. I really enjoyed Six of Crows for them traveling and having a heist not in Ketterdam but I really enjoyed this one because it was rooted in Ketterdam and was less confusing in terms of visualization.
Love love love it!
Perhaps even more than Six of Crows but only time will tell :)
