Query: What a Dissapointment!!!

This book started off great. I invested a lot of time and emotion in most of the book. I loved the characters and got really involved and read the book in two days.The last 5 chapters were slapped on the book. There was no thought put into these last chapters. There was no climax; no big secret. The end of the book was so abrupt, I couldn't believe it! It had such potential and then totally flopped. I wish I had never read it because I invested so much in the story and the characters only to be let down harshly.Don't bother. This book was such a waste of time and emotion.
