Runner by Thomas Perry

Jane Whitefield made it her life's work to help people in danger to disappear forever by assisting in their escape and crafting new identities for them. For the past five years, however, Jane has been living a quiet life in upstate New York and is the wife of doctor Carey McKinnon. One evening, a pregnant young woman named Christine finds Jane and explains that a man named Richard Beale is after her. Richard has hired six goons to get Christine back, no matter the cost. It's six against one, but the group may have met their match in Jane.... Runner is the long awaited (nine years) next book in the Jane Whitefield series. It's my first, having only read the last few stand-alone thrillers from Perry. Since I had a very hard time tearing myself away from the book, I will definitely be going back and reading the others.
