The Fifth Essence - Lawence Krauss
A really good read; no maths whatsoever, but still challenging and interesting. Whilst primarily about Dark Matter, it covers a real breadth of subject matter; Gravitation, light/ether/Michelson and Morley, Big Bang and Nucleosythesis, Particle Physics, Relativity and Gravitational Lensing, Super-symmetry...everything really. A really refreshing view away from A-Level which always seemed to be modularised with little or no interrelation between different parts of Physics.
