“Once Broken Faith” by Seanan McGuire is the latest (#10) in her October Daye (Toby) series. This series is a must read, if you like Urban Fantasy.
The book fully (and then some) lives up to the level of the previous books in the series. Toby of course faces new problems and situations, she can only solve, if she keeps developing. Luckily for us she does just that, but still remains the Toby we love.
As an extra bonus the book includes an original Arden Windermere novella.
