Book excerpt: Read Rachel Machacek's blogs and other content on the Penguin Community. One year of dating. One year of looking for love. One uproarious and touching memoir. After years of dating without a connection, Rachel Machacek vowed to try a more dedicated, less slipshod, more scientific way of finding love. So, she committed a year of her life to trying every mainstream (and not-so-mainstream) method of meeting the right guy. In The Science of Single, Rachel welcomes readers into the findings from her roller- coaster year, and although she set out looking for the right chemistry, what she discovers in the process is hilarious, unexpected, and infinitely more exciting.
