Wolf Pack by Terry Spear

Sailing to Scotia to save their lives, Isobel must fight to protect her family from all enemies.

As wolves, Isobel, her kin, and a Highland slave are on the run from her Icelandic human clan. 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 longship, and speaking Gaelic with a Nordic accent won’t make their task easy. But the human clan they’d been living with is just as much or more of a danger to them.
Alasdair is the wolf pack leader of his Highland clan when Viking raiders threaten his people. Then he spies a small Viking longship—which can mean more raiders and another fight. But what he discovers is two adult wolf females, a nearly grown male, and a female and male children on their shores. He can’t imagine the family making the treacherous journey to his land alone, but Isobel, the woman who led her people to what she hopes will be safety, captivates him like no other.

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