BLUF: More writing than action. Good story, good writing, but unsatisfying ending.
The Cuckoo’s Calling revolves around recently heartbroken Cormoran Strike. Down on his luck, and his funds, he is less than thrilled when the temp agency sends him a new, wannabe P.I. receptionist, Robin Ellacot. Lucky for him, he has a new client who is willing to pay Cormoran much more than he’s worth in exchange for investigating a clear, and well-publicized suicide. Cormoran, against his better judgment and morals, takes on this case and soon discovers that things aren’t what they seem.
There is little action in this book – it’s all words. For me, that wasn't a problem at all. I love the way Rowling writes. The downside for me is that I'm not familiar with British English. I had to look up A LOT of words..
Another aspect of the book that presents an issue to the reader is the ending. It leaves more questions than answers.
