When their plane crashes in the Amazon, four children find themselves alone in the vast jungle. Having read of explorers, Fred finds himself trying to survive like in the stories he's read about. Along with Con, Lila and Lila's little brother Max, Fred finds a map that leads to a ruined city, the children find more than they were ever expecting.

Although the adventure story was fun, the pacing was so slow that it didn't make a very good read-aloud. Often, my children struggled to pay attention, and I would suggest this book would be better suited for older children.
