Spice and Wolf (Volume 14) - Isuna Hasekura

Thanks to the silversmith Fran, Lawrence now has a map of the North. But Lawrence's gladness at the thought of finally being able to take Holo back to her home is short-lived, as upon revisiting Lenos he is embroiled in the strife surrounding a forbidden text. It is said that this mysterious book contains details of methods that threaten the land of Yoitsu itself. But in trying to get his hands on the book, Lawrence, who must return to the marketplace, finds himself running out of time to head for Yoitsu with Holo...Pressed into making a decision he may ultimately come to regret, which option will Lawrence choose?!
