I first read the darkangel trilogy in 8th grade (almost 20 years ago) and it still remains one of my favorite series. It took me until book 3 to figure out the setting is the moon (I know, I must have been oblivious). This book is wonderful except for the end. While most "happily ever after" endings feel contrived, this was a book that could have had a HEA ending and been just fine. But it isn't--and to this day I remain devastated.
