Amazon.com: The Bourne Ultimatum is a good vacation book in that Robert Ludlum seems to exhibit a knack for taking a page to say what could have been said in a paragraph, which means one book will last the entire vacation. Still, sections of this book were tight, tense, and gripping. I enjoyed my first Bourne book (the last written by Ludlum, though there are others), and think Ludlum may have underestimated Bourne's potential by aging his hero (50!) too quickly.
