Join the Unknown Adventurer on his latest adventure, this time entering dangerous waters after being washed up on a deserted island.

This was meant to be a journal of my quest to find the sea nomads, but a few days ago something happened that turned my world upside down... You are about to read an adventure story so real you’ll be able to taste the salt water on your lips. 
 
After he’s flung from a ferry after seeing something so dangerous he would be killed for his silence, the Unknown Adventurer washes up on a deserted island. Completely alone, he
puts his survival skills to the test and begins the journal he promised his younger siblings he would write.  
 
But after a while, he notices that it is not all what it seems on the island, and
something mysterious lies across the lagoon. Something he must investigate... 
 
Presented like an artist’s journal, with
handwritten sections, smudged notes and stuck-in pages and illustrated in breath taking detail, this is a thrilling tale of survival, friendship and underwater discovery.  
 
Take a deep breath. You are about to enter dangerous waters. 
 
Also from the Unknown Adventurer:
The Lost Book of Adventure and Journey to the Last River.
