This book was enjoyable to read, though less intriguing as the rest of the series. This is my all time favorite series, and Thick as Thieves is the weakest book so far. Having said that, I read the book in 2 sittings. The last book in the series, "The Return of the Thief" is supposed to be released in March 2019, and I am excited for the focus of the series to return to the strongest character, Gen. I love all the characters in this series and have mixed emotions about it coming to an end!
