The Viking Underground series ran from 2002 to 2009, producing five books that combine Viking heritage with Kenyon’s trademark paranormal romance. The Hunted kicks off the series, and later entries like Tie Me Up, Tie Me Down and Deep, Dark & Dangerous ramp up both the supernatural elements and the romantic tension.
Several of these titles were originally published as parts of multi-author anthologies before being collected under the Viking Underground banner. Besieged (2009) wraps up the series. The books appeal to readers who enjoy the combination of ancient warrior mythology and modern-day romance that Kenyon handles throughout much of her catalog.
