Not a bad story, but for unexplained disappearances I'd rather go with There's No Place Like Here. Maybe that book influenced my take on this one. I felt I wanted more. I appreciated all the different perspectives included but it felt like "so what" by the time I got done. I didn't devour this book. It's not nearly as haunting as Joyce's The Silent Land but does contain some of the same feeling of reality/unreality. Until the end, you're as willing to believe Tara's nuts as you are she's telling the truth. Though it's a book, so I lean toward the truth, anyway. 
 Tara, Peter and Richie were always together. Peter and Richie were best mates until Tara disappeared. The police suspected Richie, the boyfriend, had done something to her. Peter didn't know what happened to his sister, but he did his best to move on. Now Tara's back after twenty years and it seems she hasn't aged. Richie never really grew up, either. Peter just wants the truth. . . or a truth he can accept. 
 The most interesting part of the novel, for me, was the epigraphs.
