Query: What a disappointment

I purchased this book as soon as it was published, and couldn't wait to read it. I have finally read it, and I can't believe how disappointed I am. I absolutely loved "The Secret History", it is one of my all time favorite books that I have ever read. This book, as is her style, was fabulous when it comes character developement, scene descriptions, dark and gloomy mystery. But why couldn't she wrap up the loose ends and give the reader some sort of answer to the question of what happened to Robin? That was the only thing that kept me reading to the end.
