Spring is around the corner, and so is Ostara, the Spring Equinox. Kestrel Wallace and her cousin Bran are looking forward to warm weather and more sunlight, and to celebrating the Sabbat with the rest of their family. But Bran can't completely enjoy the change of seasons while he's dealing with older kids who are bullying him because he has two fathers, and Kestrel doesn't know how to help him.

When a new student, Jamie, joins their class, Kestrel discovers that the older boys aren't the only bullies at school. Her friend Sohana insists that Jamie is "a girl pretending to be a boy" and tells others that Jamie is lying about who he is. Kestrel can't stay friends with a bully!

Can Kestrel figure out how to help Bran and Jamie? Or will she be the next target for the bullies?
