Life of Pi by Yann Martel

Don’t switch off! This novel is not about Maths but about the need for company when survival is tough – even if your companion is a fierce predator.
16-year-old Pi is shipwrecked and left floating in a lifeboat with an adult tiger. Death seems inevitable – either by drowning or as dinner for the feline.
Pi’s experience as a zoo keeper’s son enables him to exercise some control over the animal and the continual task of finding food and water for the tiger motivates Pi to continue living.
Sharing a boat with a tiger is dangerous but preferable to being totally alone
