The Seafarer's Bride — Laura Strickland

A year ago, Magnus Tolljursson helped repel a treacherous attack from his father's enemies, and discovered he carries the berserker's seed of madness. Now he must sail to the settlement from whence those attackers came, and fulfill a promise to a friend. He doesn't know what he'll find in Husavik and never suspects he may lose his heart. In her father's absence, Embra Fritisson has been engaged in a desperate battle to keep leadership of the settlement. When Magnus arrives saying her father is dead, she fears her unstable family will splinter into factions and destroy one another. She must retain control, but how can she hope to keep her head while falling in love with the enemy?
