Book excerpt: Rachel Friedman has always been the consummate good girl who does well in school and plays it safe, so the college grad surprises no one more than herself when, on a whim (and in an effort to escape impending life decisions), she buys a ticket to Ireland, a place she has never visited. There she forms an unlikely bond with a free-spirited Australian girl, a born adventurer who spurs Rachel on to a yearlong odyssey that takes her to three continents, fills her life with newfound friends, and gives birth to a previously unrealized passion for adventure. As her journey takes her to Australia and South America, Rachel discovers and embraces her love of travel and unlocks more truths about herself than she ever realized she was seeking. Along the way, the erstwhile good girl finally learns to do something she’s never done before: simply live for the moment.
