[EPUB] The World of the White Rat Swordheart by T. Kingfisher

Halla is a housekeeper who has suddenly inherited her great-uncle's estate... and, unfortunately, his relatives. Sarkis is an immortal swordsman trapped in a prison of enchanted steel. When Halla draws the sword that imprisons him, Sarkis finds himself attempting to defend his new wielder against everything from bandits and roving inquisitors to her own in-laws... and the sword itself may prove to be the greatest threat of all.
