_ "Robert Ludlum's The Arctic Event" by James H. Cobb (Grand Central Publishing, $15.99): Despite being dead, Robert Ludlum continues to have his name atop spy thrillers. In the latest installment in his Covert One series, an Army doctor travels to a remote island in the Canadian Arctic to investigate the crash of a Russian plane carrying weaponized anthrax.

_ "World Without End" by Ken Follett (Dutton, $35): This tome should last you till spring!
