Seventeen-year-old Calliope Silversmith's lifelong friendships are transformed when she starts dating new neighbor, Max, but her life is turned upside-down when she learns the identity of the sperm donor her mothers chose.
Calliope Silversmith has never wanted anything more than her best friends Ginger and Noah, her moms, their house in the woods, and their family-run yoga studio-- except maybe knowing who her sperm donor is. When Max and his family move into the sad old house across the woods from Calliope, she realizes it's nice to get to know someone new. The stability of her longtime trio wavers as she and Max start to spend more and more time together. When Calliope finds out her sperm donor is Max's father, she and Max struggle to redefine their friendship. -- adapted from jacket
