I won this book in a giveaway, and I'm glad that I did. This is a good book which was difficult to put down. I really enjoyed reading it.
The reason I'm only giving it 3 stars is that I found the plot to be very typical YA fiction. Not very original, I'm afraid. Also, there were many editing problems, though I suppose that's to be expected with a self-published book. Lastly, the two images used for this book seemed not to fit the story in many ways, and seemed like 'stock' photos that were simply used in lieu of images that were actually created for the book. Again, most likely an issue to be encountered with a self-published book.
I would say, though, that if the premise of this book interests you, the price is very good, so go ahead and buy it and support this author :-)
