Chelsea Cain’s Let Me Go is the sixth book in her Archie Sheridan / Gretchen Lowell series. If you haven’t read the series, start with Heartsick and work your way down. For a standalone, read The Night Season. Let Me Go is not a standalone and Cain mentions a few cases and people from the other books, hence the reason I recommend starting with Heartsick.Let Me Go picks up shortly after Kill You Twice leaves off. Gretchen is still at large and for once Archie takes things in stride. When Archie receives some unsettling news, he sets out to meet with Leo Reynolds, son of drug lord Jack Reynolds and a secret DEA agent. Soon Archie finds out Jack is the one pulling the strings and Leo is being kept on a tight leash. Archie attends a party at Jack’s estate hoping to put Susan at ease regarding Leo, but what he finds has him asking questions and wondering who to trust. When Susan gets involved, Archie knows he won’t rest easy, but when a woman’s body is found, everyone is on alert and thoughts of Gretchen are in full force. Will Archie discover Jack’s secret before it is too late or will Gretchen strike again?In my Kill You Twice review, I asked how much more can Archie take and judging from the events in Let Me Go, he’s a lot stronger than I gave him credit for. It was nice to see Archie more relaxed and go with the flow versus always hard at work. I liked that he gave up the reins a bit, but at the same time I wished he wouldn’t be that hero. The one that needs to save the day and wow, does he ever! As always, my heart breaks for him and what Gretchen did to him. Just when we think he’s away from her grasp, Gretchen makes an appearance and it all goes to hell. It’s scary to think how much planning Gretchen must have done to orchestrate everything she does. Then again, I’m reminded of her use of apprentices and really do begin to question how many she has out there.I like what Cain did in Let Me Go and moving away from centralized Gretchen crimes; however, Let Me Go was bit unsteady especially when you compare it to The Night Season. Granted the differences between both books are clearly evident especially since Gretchen was in prison and here she’s still missing. Cain attempts to throw suspicion on Gretchen as the perpetrator of a few murders, but there’s a flaw. Gretchen is not sighted near these crimes and of course there are Gretchen sightings in other parts of the world except Portland. It all comes together and when Gretchen shows her card, I still had questions. Heck, I’m still not sure what to make of the final chapters involving the real culprit and Gretchen’s ultimate role. Perhaps, in the end, that’s the beauty of Cain’s writing: she leaves you asking questions.I always enjoy Cain’s books and Let Me Go was bittersweet. I like Leo and worry about him even more. I won’t go into detail because I really don’t want to ruin things for readers, but I do have to wonder how many past characters Cain will kill. It just seems a little too neat. As for Gretchen herself, I do wonder how much further we can go especially with her ability to kill so many people in x amount of time. Those of us longing for a Susan and Archie romance will probably have to reconsider after seeing what Gretchen does in Let Me Go. In Evil At Heart, we learn of Archie’s grand confession and we see bits and pieces of his relationship with Gretchen in Sweetheart, but in Let Me Go we get to the heart of it and it’s just as twisted as we expected it to be.As with the previous installments, Cain has wanting more and sadly we’ll have to wait a little longer for a seventh book.If you’re a fan of mystery thrillers, I highly recommend Chelsea Cain’s Let Me Go. Just a bit of warning: be prepared for dark humor and you might want to rethink eating before reading any of Cain’s books.This review & others are posted at Literary, etc.
