Considerring the cover and that it was free (so my expectations weren't exactly high) I was hooked, I read the book start to finish in about four hours - please do NOT allow this to deter you, I'm very much a speed reader (cover to cover on the thickest of the Harry Potter novels in less than 20 hours and that was with meal times and other breaks included).
It was all over a little faster than I would've liked, in fact I was rather upset when the story ended but that was because it was EXTREMELY well written and I have since read in excess of 30 books yet can remember this one in detail - quite the accomplishment.
The detail, narrative, plot and characters were very detailed yet not overly so. I was hooked and should there be any other work from this author I will be HAPPY to pay for it.
The ONLY reason for the 4 stars instead of the 5 is that apart from an oddly misleading cover, it was shorter than I would've liked (this did not however detract from the story itself which in no way felt rushed) I reccommend it.
