The Fifth Book of Lost Swords: Coinspinner's Story is excitement embodied in the written word.
Prince Murrat, a visiting diplomat from neighboring Culm, begs Princess Kristin to allow him to borrow Woundhealer so that he can bring it back to heal his ailing sovereign. When she firmly refuses, the Prince puts his own Sword, Coinspinner, a god forged sword that unfailingly puts the odds in it's owners favor (so long as they possess it), into play and steals the Sword of Love.
Coinspinner's web of luck, however is fickle and good fortune soon abandons Prince Murrat when he lends it to a bitter young relative who decides to keep it for his own benefit. Relying on the Sword in a game of chance, the young man soon loses it to the dread wizard Wood, who wields Sheildbreaker, a sword immune to Coinspinner's influence.
Wood immediately turns the sword against young Adrian, Prince Mark and Princess Kristin's eldest son, who is on a magical quest in the City of Wizards with a fellow student, Trilby. Caught in a web of enchantment enhanced by a web of luck woven by Coinspinner, Adrian and Trilby are nearly destroyed. But Coinspinner, always on the move, decides to take itself away from Wood at the last instant.
My favorite element of this story is the way the characters are influenced by Coinspinner, even as they try to use it to their own favor. For a lucky sword, this one seems determined to abandon it's owners at the most inopportune times. It makes for a fun story.
