This was a quirky book, with an even quirkier plot, but filled with so much greatness inbetween the humour.
Its premise is that one man, a mathematician going by the name of Andrew Martin, has discovered the pattern hidden in prime numbers and is standing on the brink of pushing human civilization beyond its borders.
The Hosts, as they call themselves, want to interfere and kill Andrew, replacing him with an alien, which is the protagonist of this story. His task is to eliminate all evidence of what Andrew Martin has proven, be it written or remembered.
While he starts his task with enough gusto, the humans that repelled him at first, start gaining his appreciation. So much even that he renounces his eternal life to become human.
The plot seems so simple but it is refreshing to see our own life, society, civilization objectively as only an 'alien' could see it. And then to have that same 'alien' falling in love with all our faults. It starts out quick-witted and humorous, but the story gets a deeper meaning the more human he feels and it is actually filled with tons of wisdom. I, for starters, am actually intrigued to read Emily Dickinson now.
