Twelve-year-old June Delancey is kicking summer off with a bang. She shaves her head and sets two goals: she will beat her anxiety and be the lion she knows she can be, instead of the mouse everyone sees. And she and her single mama will own their power as fierce, independent females.

With the help of Homer Juarez, the poetry-citing soccer star who believes in June even when she doesn't believe in herself, she starts a secret library garden and hatches a plan to make her dreams come true. But when her anxiety becomes too much, everything begins to fall apart. It's going to take more than a haircut and some flowers to set things right. It's going to take courage and friends and watermelon pie. Forget second chances. This is the summer of new beginnings.
