Image by Catherinette Rings Steampunk via FlickrI received The Puzzle Ring as a gift from Kate Forsyth - thanks, Kate! It was a great read and kept me up past my bedtime for a few nights.
Forsyth has many books listed with Amazon but in the US, this one is not listed, so you'll have to go further afield to find it. One option is Amazon UK and another is the Book Depository.
I'll be hosting Kate Forsyth here on February 11th to answer a few questions about the book as part of her blog tour.
