The ongoing story of Miriam Black's uniquely horrific life remains utterly spellbinding. Lots is made of the harshness, grit and grime of these books, and it's true, Wendig's characterisation is uncompromising. But you'll also be hard pushed to find books with more poetic prose. It's a trip. A bad trip.
The power of the series is that Miriam is not just a Chosen Oddity to thrust into odd situations; the books are all about her. She's the avatar of agency and self-destruction, and this third instalment finally explains those remaining gaps in her horrible history, and develops the supernatural world Wendig is building in spectacular ways. There are a lot of answers in this book, and whole new colors to the lady herself.
Wendig has quickly become one of my all time favorite authors, and I'd open a vein right now if I thought it would bring Thunderbird out sooner. Can't recommend these books highly enough, this one in particular.
