Hugely recommended - not just for established fantasy fans; I think this would also make a great entry point for people who haven't read too much of it and are looking to dip a toe into the genre.
We also have a review of de Castell's [[Spellslinger by Sebastien de Castell|Spellslinger]].
Despite this being a fantasy, the closest thing I've read to it recently is another swashbuckler with a superb group of friends as the heroes, the classic [[The Three Musketeers by Alexandre Dumas and Will Hobson (translator)]]. If it's definitely fantasy you're looking for more of, another series that we think is a really fun read is [[The Copper Promise by Jen Williams|The Copper Promise]] and [[The Iron Ghost by Jen Williams|The Iron Ghost]], both by Jenn Williams.
