In the Woods - Tana French

This book was really long and left me feeling cheated. It is difficult to explain why without spoilers and I don´t want to do that. I was really drawn in by the initial story about the three kids that went into the woods and only one was ever found. I was intrigued by the potential for the new case to be related to the old one. I found myself wondering how anyone, especially a murder detective, could be so dumb, moody, and odd. I stayed up all night to finish the book only to be annoyed with the ending.  Will I read more in the series?  I´m still on the fence about that.  Maybe I´ll try one more, after I´ve forgiven the author......if I do.
