Sagittarians are adventurers, so they love to read books about travel, adventure and action. Some good reads for this sign include "The Life and Times of the Thunderbolt Kid" by Bill Bryson, "Going Places" by Michelle Roehm McCann, and "The Gap Years Book" from Lonely Planet.
People born under this sign enjoy novels of intrigue that are set in a foreign location. Some great books for Sagittarius would include the Hitchhiker's Guide to the Galaxy series by Douglas Adams, the Carmen Sandiago series for teens, and international spy thrillers by authors such as Ken Follett or John LeCarre.
A Sagitarrian can pass several happy hours flipping through travel guides (or catalogues), fantasizing about their many future adventures. Books that teach foreign languages will also be enjoyed by Sag.
