A fantastic follow up to The Nine! Steampunk fantasy and adventure that takes the readers on an incredible journey across continents, through the skies, and in the dark underbelly of the city. The book of secrets, the book that holds the fate of humanity, has been lost and now it's in the wrong hands. It's up to the unlikeliest bunch of people to recover the book and decipher its secrets before their universe is forever altered. Rowena Downshire has no idea how central she is to the book's secrets, all she knows is that she has to help the alchemist and some other mercenary allies track down the book. Their chase leads them far across the skies to the Grand Library where there is more than meets the eye. Full of adventure and tight plot lines, this book will take readers on a breathless race against time to find the book. I will note that this is not a standalone book and it is crucial to read the first in the series before attempting this, it had been nearly a year since I read the first one and even I needed to reference back to it!
