Last Night in Montreal by Emily St John Mandel

I was hooked immediately by the writing and storyline in this recent novel.  It's about a young woman, Lilia, who has on the move for her entire life. As a child she was abducted by her father (to rescue her, we find out later, from her abusive mother, from whom he is estranged.) and then spends her childhood and adolescence traveling constantly and changing identities. She is haunted by an inability to remember her childhood, and she moves from city to city, abandoning people all along the way. She is always being followed by a private investigator, who refuses to "turn her in," because he knows that she cannot be returned to her mother. When the book opens, she is with Eli, who then follows her from New York to Montreal. He meets up with Michaela, who has befriended Lilia, but won't tell Eli where she is until he reveals a truth about her that she revealed to him, swearing him to secrecy.  Mandel s characters will resonate with you long after the final page is turned. I enjoyed this very much, but it was disturbing.
