I love this series as a whole and binged the three existing books. They all manage a great mix of humour, depth and thoughfulness. It was cool that this book took us outside Sunder City for a longer period of time. The case and the mystery were exciting along some fascinating new characters we got to meet. The ending was heartwarming and heartwrenching at the same time. Only tiny downside is that the solution to the mystery felt very similar to the last book towards the end.
