Books in the Finnegan Zwake series

Thirteen-year-old Finnegan Zwake, his uncle Stoppard -- a bestselling mystery writer -- and their friend Jared are off to an archaeological dig in sunny Aguilar, land of giant cacti, jungles, and dinosaurs. Dead ones, that is.While Finn and his uncle are digging up treasure left behind by Finn's archaeologist parents, now mysteriously missing, the crew is digging up very valuable dinosaur eggs. But digging too deeply can stir up trouble, not to mention a murder, or two, or three....

Finn and his mystery-writer uncle head to Iceland in search of the Haunted City of Tquuli, where Finn''s archaeologist parents were last seen before their odd disappearance eight years ago. Finn doesn''t believe the creepy legends about the Haunted City and the ancient Vikings who lived there -- until a member of the rock-climbing expedition vanishes from inside a sleeping bag...one that was dangling a hundred feet from the base of an icy cliff! Then another climber disappears, leaving a trail of footprints that abruptly end in a field of snow. Is it modern-day murder, or the revenge of phantom Viking warriors?
