Wicked Bugs: The Louse That Conquered Napoleon's Army & Other Diabolical Insects

Things that make you go 'ewww'.

Excellent read but not for the easily squeamish. Amy Stewart vividly describes what many of the world's pests do, making my partner insist that I stop reading sections out loud to him as they were really too disgusting. But if you like nature, or any interest in entomology, this book is a fascinating, entertaining read.
