Fossegrim (Undraland #3)

With half the team left behind or assumed dead, Lucy, Jamie and Foss sail to Fossegrim, a land where Foss is one of the four most powerful men, and Lucy is blonde chum for slave-traders, thieves and the like. Keeping her head down is the least of Lucy’s concerns when she gets thrown with other abductees and put up for auction.
With her guardian gnome MIA, Lucy has to learn to work with the one person who hates her most, leading her to make dark decisions she never would have considered. Foss takes Lucy through the dangerous parts of his land as they fight with and for each other. The angry Fossegrim sacrifices much, hoping the woman he despises will somehow prove herself worthy of fighting by his side.
