here you go, all these books are very easy to read, but deal with pretty complicated subjects
The Blind Watchmaker, The God Delusion, Climbing Mount Improbable and the Selfish Gene by Richard Dawkins. At least two of these are seminal... The Blind Watchmaker shows how natural forces designed the best organisms, from bats, to polar bears, to fruit flies. If you want to know how evolution works, this is the book to read. The Selfish Gene, well, was an earlier work and what can I say, it invented memes! It deserves a read for only that.

Freakonomics - rogue economists explains how the world works in some bizarre ways, full of fun stats, but it never gets tiring, and each of the chapter is presented in this format first a ridiculous question is put forward, but then it slowly start making sense as the chapter explains more
Quirkology by Richard Wiseman - this is like Freakonomics, but for psychology instead of economics. Fun part is the book starts of with an actual psychological test! (that get's resolved at one point in the book)
The Magic Furnace by Marcus Chown - this one is on cosmology. If you are curious about where and how everything came to be, this is the official science book to read. It goes into the details. This book reads like an epic saga of matter - where all the particles in the universe were made and in what conditions they came about. Each chapter begins with a quote from diverse sources like Blake, Newton and Blade Runner. If you have ever heard the idea that all things are made out of particles ejected from supernovas,
Each and every one of us is stardust made flesh
it is from the prologue of this book.
The Universe Next Door by Marcus Chown - If you like outer space, wormholes, the big bang, then pick this one up. It explores 12 cutting edge theories, from panspermia to dark matter, this book repeatedly covers a bunch of out there concepts.
) after a long time. Highly recommended.
