Truefact: I have not paid any attention at all to the post-Hogwarts literary career of JK Rowling, so I had NO idea that she was the author behind the pen name. I selected the book based on reviews on Audible, and it sounded like fun. I was about a quarter of the way into it before I read the Amazon page and went wait, hey, this is Rowling?
I am enjoying The Cuckoo's Calling (Cormoran Strike) very much, and definitely will follow the entire series. Cormoran Strike is an interesting detective, mostly because he's so damn professional and realistic, ex-military guy that he is. I'm about halfway through the first book and will definitely read the second. But the reviews on Amazon make me feel almost sorry for JK Rowling (poor wildly successful billionaire that she is).
Because as soon as anyone knows she wrote it, they expect another Harry Potter. In every realm of fiction, she is expected to re-create a once in a generation wildly successful epic.
If any other author had created Cormoran Strike, he/she'd be credited with creating an interesting, fun, quirky, charming new entry into a very established genre. It's smart, quirky, well written. But the reviewers love to point out how they Somehow Expected More, and This Is Not Original. I'm glad Rowling is still writing and I'm enjoying her detective series; it's a great read. It's "no Harry Potter," because it's not supposed to be.
