This book is about a boy called Beck Granger who gets shipwrecked with a small group of passengers. But Beck is no ordinary boy. He is the world's youngest survival expert. He has to keep a small group of passengers safe. But someone wants him dead, that is, if the sharks don't get him first. My favourite part is where he has to escape from a secretive oil rig that's about to explode, owned by LUMOS, the energy company whose plans he keeps messing up. They always invest in ideas that ruin the environment. When Beck is taken to the oil rig, called Island Alpha, he disrupts the computer systems to open the security doors. My favourite character is Beck Granger because he has good plans and knows a lot about survival in the wild. I learned that sharks can smell a drop of blood from a olympic swimming pool length away.
