They are helped along by Ansgar the monk, who is looking for his stolen books. A series of clues point them toward a mysterious place called Mimir’s Well. But the villainous Ivar and his clumsy assistant Grim are hot on their trail, eager to get the treasure for themselves. Once again Siri has to use all her cleverness as she faces baffling riddles and dangerous traps. If she makes it through, perhaps she may find the answer to the greatest riddle of all: what precious treasure lies hidden in the depths of Mimir’s Well?
