First Family by David Baldacci (2009)

Seemed appropriate to read about the first family now that we are so focused on the current administration. 12 year old Willa gets kidnapped, her mother killed and the First Lady asks Sean King to investigate on his own, even though the FBI and other agencies are already involved. He and Michelle Maxwell floow various leads and end up in Alabama, where Sam Quarry has been brooding on the tragedies that have befallen his family. How are these connected? We really only find out in the end. Sam Quarry is an interesting "bad guy" with a lot of good traits. He supports and saves numerous people along the way - Fred - the Native American living on his land, Gabriel and his mom, whom he took in to his house. He even saves Willa in a way.
