Between You & Me by Marisa Calin
Phyre knows there is something life-changing about her new drama teacher, Mia, from the moment they meet. As Phyre rehearses for the school play, she comes to realize that the unrequited feelings she has for Mia go deeper than she’s ever experienced. Especially with a teacher. Or a woman.
All the while, Phyre’s best friend—addressed throughout the story in the second person, as "you"—stands by, ready to help Phyre make sense of her feelings. But just as Mia doesn’t understand what Phyre feels, Phyre can’t fathom the depth of her best friend’s feelings . . . until it’s almost too late for a happy ending.
This debut novel is told in a screenplay format, and there's also the mystery of Phyre's best friend - is "you" a guy or girl? Add your review of "Between You & Me" in comments!
