I love that this series seems to be following it's own path, taking us where it thinks we need to go and shunning conventional series rules. After the reveal about Jack and Jill at the end of the first book, instead of continuing the story, this book instead takes us back to their past, and shows us the world they tumbled into as children.

This pulls from Frankenstein and Dracula (although those names are not used), as Jack chooses to become the Doctor's apprentice, working hard and enjoying a simple life in the village, while Jill becomes one of the most feared of Dracula's potential brides, her obsession with him driving her beyond the brink of madness to try and please him. 

Much like the first book, by the end of the story I didn't want to leave the main character, this time Jack. There's numerous characters now that I want to see in future books, and I'm hoping that as the stories are pieced together, I'll finally get closure for my favourite characters. I love the unpredictability of this series.
