I'm reading A Song Of Stone by Iain Banks, which is good if rather overwritten.
I've also recently read Dowsing: A Journey Beyond Our Five Senses by Hamish Miller, of which the first few chapters are interesting and informative, and the last few chapters are the ramblings of a lunatic (ley lines, auras, OOBEs, faith healing, cosmic energy and the Knights Templar all figure).
