I'm very disappointed that Wild Fire is the last book in the Shetland series. I have enjoyed each and every book of this series. I have found that all of Ann Cleeves' police procedurals hook you from the beginning and don't let you go until the very surprising ending. Her characters are all well-drawn and the plots are always unique. The murderer in her books are always hard to solve. She keeps the clues close to her chest. Jimmy Perez is my favorite character but I was not happy with how he treated Willow about her news of her pregnancy. If you haven't read this series yet, you need to start with book 1, Raven Black. Highly recommended for those who love mystery thrillers.
