Book Review - Unseen by Karin Slaughter

I have previously enjoyed Slaughter's crime novels very much and I was puzzled at how long this one took to get going. I'm not sure if it was about a 1/3 or ½ way in when it started to actually come together and I think she has seriously miscalculated the plotting to let the opening go on so long. If you persevere (and I only did because I am a fan), you get to an intricate collection of deceptions that eventually turn into as satisfying a plot as a story that involves drugs, prostitution and pedophilia can be. Agent Will Trent's burgeoning relationship with Dr Sara Linton hits a few bumps in the road and hangs in the balance but the process of being with her has changed him forever. Sara's rocky relationship with Detective Lena Adams continues and they are all caught up in the maelstrom of violence as various investigations crash together at the end. Wendy
