The Guardian Groom by Lucy McConnell

Bree Phelts is shy, enjoys reading, and spends her free time helping her mom. Her biggest worry is figuring out a grand prize for the summer reading program. Her black and white life is splashed with color when Owen Mattox, a professional football player, asks her to step out from behind the refreshment table and dance. He’s wrong for her on so many levels but just what her heart needed to wake up.

Devastated when he’s dumped by the only woman he ever imagined marrying, Owen Mattox pulls his heart in tight and doesn’t let go. He’s worked so hard to isolate himself from love—and the pain that comes when it’s lost—that he practically a recluse. He doesn’t even hang with the other Texas Titans players and builds his home outside of Dallas for privacy. The fewer people in his life, the fewer chances of getting hurt. But he can’t deny his interest in the quiet librarian and once they dance, he’s hooked.

But Owen doesn’t open his heart easily which means Bree will have to overcome her shyness and be her own hero—instead of reading about one—in order to save the love that’s budding between them.
