Just when you think surely she can’t possibly make another installment as good as the previous ones Jeffy Kennedy produces this excellent book. Yes, it provides enough backstory on its own that you could start here but why deny yourself? For long time fans it provides deeper world building and furnishes those nerdy details you’ve been wondering about. Of course Deborah Barnes does a beautiful job even if you haven’t developed a pavlovian response to her voice from listening to other books in the series.
