Short, easy to read, entertaining mystery. I enjoyed it.
Finnegan Zwake Finn and his mystery-writer uncle head to Iceland in search of the Haunted City of Tquuli. Finn doesn't believe the legend of the ancient Vikings who live there--until a member of a rock-climbing expedition vanishes from inside a sleeping bag--one that was dangling 100 feet from the base of an icy cliff. Is it modern-day murder, or the revenge of phantom Viking warriors?
