Philomena Sparks and The Curse of the Big Ben has been out there for some weeks actually, and it already has two five star reviews in Amazon. The ones who have read it told me they loved it, that they could picture themselves in the Victorian world described in the book. Also, they loved the illustrations, which enhance and capture the mysteriously dark atmosphere of the story.
The book is available in print (paperback) and in electronic format.
Here is a list of all the places where you can find it and download a preview if you like.
