Well my favourite book is Perfume: Story of a murderer by Patrick Süskind.
It's about a man named Jean-Baptisse Grenouille who is born in 18th century France. He has no scent of his own but is born with an almost super human sense of smell. He can pick up every scent from miles around, store them with his incredible memory, break them down into their most basic elements and then rearrange them to create scents that don't even exist; all in his head!
However, he becomes a serial killer because he becomes obsessed with creating the worlds best perfume. So he kills virgin girls and steals their scent to create a pheromone cocktail almost. It's the most incredibly deep, powerful, beautiful, painfully honest and disturbing fascinating book I've ever read.
If this has interested you, I'd suggest watching the 2006 movie first. It does great justice to the book but as always, the book is undeniably better.
