From Seven Till Dawn: Book One of The Tablets series

ABCDE Blanks is a man with no name. A strange wooden tablet bearing an ancient message has washed up on his beach in the South China Sea, and there are six other tablets that he must find or the world will end. From Seven Till Dawn is a wryly funny adventure story unlike anything you've ever read before as its heroes romp across three continents. Contains adult content. Not recommended for young readers.
