Wolf Pack by Terry Spear

As wolves, Isobel, her kin, and a Highland slave are on the run from her Icelandic clan and now they must find a way to live in peace in Scotia without anyone discovering they are wolves or Vikings. Wearing traditional Icelandic clothes, sailing a Viking longboat, and speaking Gaelic with a Nordic accent, it won’t be easy.

Alasdair is the wolf pack leader of his Highland clan, in the middle of adding fortifications to his castle when he spies what he thinks is a small Viking longboat—which can mean raiders and a fight. But what he discovers is two adult wolf females, a nearly grown male, and a female and male bairn on their shores. He can’t imagine the family making the treacherous journey to his land all on their own, but he’s captivated by Isobel, the woman who led her people to what she hopes will be safety.

Not everyone in his pack welcomes having Vikings living among them though. And Isobel is a wild and unpredictable woman, which fascinates him all the more.
