Vince Flynn's protagonist, CIA counterterrorism operative Mitch Rapp, prefers more, er, flesh-and-blood characters than Hamilton's Blake, but that hasn't impeded the success of author or hero. Rapp's previous three outings—Term Limits, Transfer of Power and The Third Option—have spent a total of 14 weeks on our charts. Now political thriller #4, Separation of Power, is off and running, marking its second week in our top 10. Flynn's in the midst of an eight-city tour; Pocket Books reports 125,500 copies in print after three printings.
