Percy Jackson and the Lightning Thief (Percy Jackson #1) - Rick Riordan

Half boy, half god, all hero.

Look, I never asked to be the son of a Greek god. I was just a normal kid. . . until I accidentally vaporized my maths teacher.

Percy Jackson is having a bad week. His life has gone from totally normal to monsters-from-Greek-mythology-randomly-appearing kind of strange. Worse still, the king of the gods thinks Percy has stolen his all-powerful lightning bolt - and it seems making Zeus angry is a very bad idea.

Now Percy and his friends have just ten days to catch the true lightning thief and stop all-out war from erupting on Mount Olympus. What could possible go wrong?
