‘I Am Number Four’ by Pittacus Lore
Teenage Fiction. Friendly alien comes to Earth from another planet, he is number four of nine in total, only a load of evil aliens follow him to kill him.
The evil aliens, for some reason or another, have to kill the nice aliens in number order, number three is dead, so number four is next.
It’s not a bad book – it’s the first in a series of six – it’s also been made into a film.
