Summer Rush by Katie Winters

Thousands of miles away, in the heart of Venice, a secret is exposed that will change the lives of the women of Martha’s Vineyard forever.

Jack Potter has been dead for nearly two years when Janine receives word from his lawyer, explaining that Jack’s biological mother passed away in her home in Italy. She’s left a will.
With Alyssa and Maggie both pregnant, Janine sees this trip to Italy as a final family vacation before everything changes. But when they arrive, they learn that Teresa, Jack’s mother, was a very unique and strange individual, who’s created a sort of “scavenger hunt” through Venice for her remaining family members. If they “win” her game, they can have what she’s left them in the will.
