Query: Pleasurable read

Holland devotes 150 pages to the building of the Persian dynasty and its progress toward world dominion; then he smashes his way westward describing the politics and tactics of Athens and Sparta. The battles to repulse the invasion are given plenty of context and make for good reading.This was an enjoyable airplane book. The maps are in just the right places; two sections of black-and-white photographs. Timeline at the end; I would have liked a cheat sheet list of the major historical characters in the book (I travel with my family -- it's easy to get distracted).
