Trouble always seems to find Steve Grendon and Sim Jones. This time, they are far from home on an island right smack in the middle of the Wisconsin Dells they thought was deserted. Sim is practical, logical, and doesn't like surprises. Steve is imaginative, carefree and--truth be told--the one who typically invites the trouble. They just wanted to get away for some camping and fishing, to do something besides let their summer vacation slip away from them. But they didn't expect to encounter the ghost of an Indian chief who made it very clear he did not want them on his island! Undeterred, the boys quickly find themselves on the trail of the ghost and, before they know it, discover they are the ones being hunted. Fire Bear, a young Winnebago Indian the boys meet on their trip, may be able to help them solve the mystery. But whom do you trust so far from home when being hunted by a ghost?
