Triple Shot Bettys in Love

A small town. Three best friends. And a love triangle like no other. Geena is freaking out. She's been going out with Ben for five months, their relationship is comfortable and perfect, and then Bam! He's suddenly putting the pressure on to be way more physical. She's not sure she's ready. Enter Mr. Rex Sands, Geena's delectably hot and brilliant English substitute teacher (he speaks to her soul!), on whom her best friend Amber develops an immediate crush when he stops by the Triple Shot Betty coffee shack.
Amber needs Geena's help talking to him because he is such an intellectual, so Geena finds herself writing love notes, MySpace messages, and texts to Mr. Sands under Amber's name. And he writes back! Geena is just doing it all for Amber (sort of), so it's not technically cheating on Ben .
