Nordic Nights by Lise McClendon from Books In Motion.com

Hank was found standing over the body of visiting Norwegian artist Glasius Dokken. When Hank won't say a word in his own defense, it falls to his step-daughter, Alix Thorssen, to clear him and uncover who actually sent Dokken, the painter of myths, to Valhalla. With ancient legends seeming to spring to life around her, and with very real bullets being fired through the windows of Alix's art gallery, her investigation could end with a Viking funeral...it may all be hidden in the secrets inscribed on some ancient rune stones.
