High Balls by Tara Lain

Though only twenty-six, single father Theodore Walters lives with his head in the clouds and his feet firmly planted in reality. At the center of his life is Andy, his seven-year-old son, with whom he shares no DNA, though nobody—including his religious-fanatic in-laws—knows that, and Theodore will do anything to keep them from finding out. Theodore works hard to get his PhD and the tenure and salary that might follow to make a better life for Andy—but the head of his department thinks his dissertation on Jane Austen and romance novels is frivolous.

Theodore’s carefully planned life goes off the rails when he walks into a popular Laguna Beach bar and meets the bartender, “Snake” Erasmo, a pierced and tattooed biker who sends Theodore’s imagination—and libido—soaring. Snake has even more secrets than Theodore and couldn’t be a less “appropriate” match, but he might be the only guy with the skills to show Theodore that happily-ever-after is for real.
