The Handmaid's tale: The Last 50 pages

I'm not very happy with the ending of this book. While reading most of the book I kept thinking I will find out the answer at the end. But now that I have read the end we don't find out. The ending doesn't tie up the answers in the end. I still want to know what happened to Luke and her daughter. Where are they now? We never find out. The story has too many cliffhangers.
