I don't think there's a specific category for Hap&Leonard stories: they are gripping thriller and very funny at the same time. They feature a copy of likeable characters who are also excellent PIs.
This is a collection of novellas and it's another page turner I couldn't put down.
Almost all the stories were new to me and I had a lot of fun: there's action, gore, and plenty of humour.
I assume that Hap&Leonard is a sort of bookish cult and I know plenty of Italian that love this series and consider it their favorite.
As I'm a member of this cult I think that more people should be reading this stories as they're well plottted, highly entertaining, and a lot of fun.
That said I strongly recommend this book.
Many thanks to Tachyon Publications for this arc, all opinions are mine
