The Lovers - John Connolly
                  Series

The is the 8th in the Charlie Parker series and I could not put it down.
We learn about Charlie's past, about his father, and about the dark shadows that seem to be hunting him. 
 I was really struggling with books 6 and 7 and was wondering if I wanted to continue with the series but this book brought back my interest in Charlie Parker.  So I will put   "The Whispers", book number 9 next on my TBR. 

Goodreads Summary:
Charlie Parker is a lost soul. Deprived of his private investigator's license and under scrutiny by the police, Parker takes a job in a Portland bar. But he uses his enforced retirement to begin a different kind of investigation: an examination of his own past and an inquiry into the death of his father, who took his own life after apparently shooting dead two unarmed teenagers. It's a search that will eventually lead Parker to question all that he believed about his beloved parents, and about himself.But there are other forces at work: a troubled young woman who is running from an unseen threat, one that has already taken the life of her boyfriend; and a journalist-turned-writer named Mickey Wallace, who is conducting an investigation of his own. And haunting the shadows, as they have done throughout Parker's life, are two figures: a man and a woman who seem driven to bring an end to Charlie Parker's existence.

Haunting, lyrical, and impossible to put down, "The Lovers" is John Connolly at his best.
