Cordell, M: Blaze of Valkyries

Five shiploads of Vikings against one.
This isn't her first battle with such steep odds, but this is Dyrfinna's first as commander -- and she doesn't want to see her crew be killed off by a much greater foe before they get a chance to revenge their friend Thora.
But some of these foes are called the Child-Killers, led by the bloody-minded Nauma, who glories in dealing pain and death.
Dyrfinna and her crew manage to escape to an island in order to better defend themselves as their ship goes up in flames behind them.
Here they make their final stand, surrounded by the enemy. If the rest of the Queen's fleet doesn't find them, and soon, Dyrfinna's crew is going to die here. She's doing everything in her power to keep them all alive so she can revenge Thora and bring everybody home -- but on this haunted island, the past keeps coming alive, and the dead will not rest.
Even worse, Dyrfinna discovers that, if her crew dies, these child-killers plan to travel on to Skala to slaughter their loved ones ... including Dyrfinna's mother and little sister, who she swore to protect.
Set in a new, Norse-inspired world, and packed with magic, adventure, and dragons, A BLAZE OF VALKYRIES is the book #2 in an epic new fantasy saga from Melinda R. Cordell.
