The Secret Love Letters of Olivia Moretti

Probst’s engaging if sometimes clunky latest (after Our Italian Summer) follows three American sisters as they visit Positano, Italy, to find answers to mysteries unearthed following their mother’s death. Former ballerina Pris gave up her career for love but has grown apart from her busy lawyer husband, Garrett. Her younger sister Dev, a workaholic NYU professor, judges their youngest sister, Bailey, for hooking up with guys and never committing. After their mother, Olivia, dies, the siblings find love letters to and from “R” stashed among Olivia’s things, along with a deed to a cottage she owned in Italy. The women also discover Olivia planned to meet R again on her 65th birthday, which would have been a few months away. So they travel to Italy and stay in the cottage, hoping to find R. There, handsome neighbor Hawke catches Dev’s eye and Bailey hits on him, reviving an old feud between the sisters over an ex-boyfriend of Dev’s. Moretti’s depiction of sibling affection and tension is on point, and the plot involving Olivia’s secrets has some momentum, but the prose is often lackluster (a pair of eyes are described as “Listerine blue of the sea”). Awkward phrasing aside, this diverting story should still hold readers in its sway. Agent: Kevan Lyon, Marsal Lyon Literary. (Mar.)
