Between you & me

Phyre is a girl who doesn't know what she wants. She loves theater, but when Mia, her new theater teacher shows up, Phyre's feelings go haywire. She feels like she loves Mia, but that love goes unrequited. Meanwhile there is "You"--Phyre's best friend in the novel's screenplay character cast--who is constantly by her side, who might just feel love for Phyre in the same way Phyre loves Mia.
