Ember’s End (Green Ember Book 4) (S. D. Smith)

Scout’s seventh adventure reacquaints us with his three friends and introduces some new characters. One is Uncle Bob, long absent in North America but now back in the old country where he and his wife settle into a small but honest-to-goodness castle!

Naturally Tom and his friends, including Scout, are invited to spend the summer holidays at Uncle Bob’s intriguing house. Actually, the invitation is more like a challenge: Uncle Bob pretends to have a low opinion of “modern youth;” he thinks they’re soft and over-pampered.

To prove him wrong, Tom and his friends decide to travel on foot. But on the journey, little goes right: disasters follow their footsteps and danger is their constant companion.

While Tom and his two friends are making plans for a vacation, Carl’s father announces that he has acquired a sailboat, as part of a business deal. The three boys see the chance for a very unusual holiday.

Their peaceful sailing trip is sabotaged when they run into a gang of notorious carnival followers who put on sidewalk shows as a cover for more profitable sidelines. After a confrontation with the gang, the three sailors and Scout find themselves in trouble with the police. Their attempt to clear themselves leads to a wild chase through rivers, canals, and lakes. When at last the boys come face to face with the gang and its ruthless leader, they are stranded on an island in the middle of an isolated lake. In the showdown they are all alone — except for Scout.
