Setting the stage with information on what tsunamis are and how they come to be, the book goes on to present scenarios in graphic novel format from three major floods or tsunamis. The three events depicted are the December 2004 tsunami in Southeast Asia, the Great Flood of 1993 that wrought havoc on U.S. states along the Mississippi, and the tsunami that hit Lisbon, Portugal, in 1755.
