When 17-year-old Calliope meets her new neighbor Max, their connection is instantaneous, but the revelation of her sperm donor’s identity changes everything.


Calliope Silversmith has always had just two friends in her small Pennsylvania town, Ginger and Noah, and she's fine with that. She's never wanted anything more than her best friends, her moms, their house in the woods, and their family-run yoga studio--except maybe knowing who her sperm donor is. Her curiosity has been building for years, and she can finally find out this summer when she turns eighteen.

Then Max and his family move into the house across the woods from Calliope, and she immediately feels a special connection with her new neighbor, one that feels different than just friendship. The stability of her longtime trio wavers over the next few weeks as she and Max start to spend more time together.

But when Calliope makes contact with her sperm donor she learns a surprising truth: her donor is Max's father. How is this even possible?

As she and Max struggle to redefine their friendship now that they know they’re half-siblings, Calliope realizes she has much to gain by recognizing and accepting that family is both the one she has been born into, and the one she chooses to make.
