Thalassophile

For someone who has a natural tendency to sink and general angst towards beach holidays, I really loved reading two books on the sea, 
1) Un océan d'amour by  Wilfrid Lupano (Author), Grégory Panaccione (Illustrator) and 
2) Other Minds: The Octopus and the Evolution of Intelligent Life by Peter Godfrey-Smith.
