How dare the author leave me on that emotional cliffhanger with the next book not coming out until September! I will always listen to these on audible because the narrator is *chef’s kiss* - just everything you want in a dream narrator. This installment finds Strike and Robin investigating a cult. Not just a small one either. One that has ties to celebrity and has been “controversial” for decades. However, when a wealthy family wants help talking to their son who is immersed in said cult and cut off communication, Robin decides to go undercover. For months she is indoctrinated, starved, over worked, and punished by this brutal cult. But Robin is stronger than they think. And her connection to Strike comes through beautifully. This is the best installment so far. It has the cult, the tension where I was literally talking out loud to the characters, and then of course the relationship between Strike and Robin. Robin is now in a relationship with Ryan Murphy who we met the last book, but will that one prevail? Strike of course makes the mistake he always seems to make when he is trying to get over Robin, but I won’t spoil it, you do see some real growth from him here. And then the ending. Listening to the lay out of the case was great, but it’s the very end in a moment between Strike and Robin with Murphy interrupting, that I am not sure I will forgive the author for. I need resolution!
