This is the third in the Cormoran Strike mysteries by Robert Galbraith (otherwise known as J.K. Rowling).
I enjoy these books. The mysteries are great, they are always so different then the last, and I can never figure them out before the end, which I love. This one all about Cormoran's past when someone sends his partner Robin Ellacott a severed leg to the office. He must delve in deep to catch someone from his past before they can do any more damage to anyone, including Robin.
The one thing that does bug me about these books is that it takes me what feels like forever to finish them! I don't know what it is, but I can't read these quickly. I've tried too. Doesn't happen. It's something about her writing that takes me so much longer to get through. That's a good thing in a way, but when the TBR is a mile long and you wish you could simultaneously read 4 books at once, it is kind of a pain.
There better be a new one and it better be soon because the ending has left me with so many questions and I seriously need answered. Not about the mystery, but about the main characters and their lives. J.K. Rowling creates such an awesome story with such complex and interesting characters that you just can't get enough of.
Recommendation: If you read the first two, read this. If you haven't read any of these books yet, please please please do. They are made for the lovers of stories and the lovers of a good mystery.
