The Look of Love by Sarah Jio. The book is being released by Plume on November 25, 2014.
Amazon says this about the book: Born during a Christmas blizzard, Jane Williams receives a rare gift: the ability to literally see true love. Jane has emerged from an ailing childhood a lonely, hopeless romantic when, on her twenty-ninth birthday, she receives a card from the midwife who delivered her. Jane must identify the six types of love before the full moon following her thirtieth birthday, or face grave consequences. When Jane falls for a science writer who doesn’t believe in love, she fears that her fate is sealed. Inspired by the classic song, The Look of Love will utterly enchant Sarah Jio’s rapidly growing fanbase.
