I quit reading when I realized that this wasn't a full story in itself.  I have read series before that at least held their own story for that book and continued in others.  But I was half way through this book and quit.  I just found out the story line when I was half way through.  That doesn't bode well for the ending.  It will be a huge cliff hanger for sure and I don't go for that when reading.  At least it was free on Kindle since I would have to pay alot to continue the story if I chose to.
