London, 1840. At the height of Victorian hypocrisy, two men meet and fall in love. Their romance is forbidden, punishable even by death, but their passion blossoms thanks to a paper Valentine. Saint Valentine's Day has become a new and very popular day for lovers. Thousands of Londonites are clamouring for the ideal romantic gift. While men buy chocolate and posies, they yearn for something more unusual, more personal. Enterprising brothers Aldon and Samuel Barnaby hit upon the idea of paper Valentines, creating lavish presentations decorated with silk, lace, and paper flowers. Aldon is fortunate to have his perfect valentine going to his expectant wife, Geneve, but Samuel still longs for his own true love, pouring his heart and soul into his beautiful creations. Samuel's romantic verses inside his paper Valentines are in huge demand, yet not a single local girl can lay claim to his heart…because his passion lies not in a woman, but another man—Jude, a handsome but shy widower. Jude's heart, haunted by grief, hasn't been ready to consider marriage again. But slowly, through his inclusion in the Barnaby family's lives…and his frequent excursions to stop and stare at the Barnabys' shop window…he begins to wonder in what direction his future lies. Can Samuel possibly allow his heart to explore love with another man? Could Jude ever love him in return? He sends Jude an exquisite, anonymous paper Valentine, not suspecting that his entire world is about to be turned upside down…
