Bests & Worsts Reviews from Amazon

I bought this book and then the second but it seems to be a trilogy or series and there hasn't been another book in over 7 years. Don't waste your money getting started on this since you will be disappointed that there are so many loose ends and lack of completion of the story -- you are left with a total mystery about the main character which is never explained. Honestly, I don't think this should be sold by Amazon without a warning.
