Mercury Retrograde: Its Myth and Meaning, by Pythia Peay, from Jeremy P. Tarcher Inc., ISBN 1585423165. Mercury retrograde happens three times a year, and most people know that it means there will be snafus in all things mercurial - that is, contracts, travel, communication, and commerce. Author Pythia Peay unveils the period's deeper meanings. She traces its history and mythological underpinnings, and offers a practical, incisive analysis of how Mercury retrograde can be a tool for growth and insight. We might actually benefit by taking a break from the usual, harried way of going about things, and consciously working with the slower pace of Mercury retrograde.
