Have read every Baldacci book. I love this author. However the Search for Atlee Pine's sister, Mercy is becoming a jumble of other agents and Alphabet Agencies, lies, cover ups, murder, mayhem, conspiracy and, am afraid to say irritation. I haven't warmed to Pine (unlike Puller and Decker). Have Mercy on us David and let miserable Atlee find her. A glossary - for non US readers might be a good idea.
