On the Outside by Siera Maley [wee_wiwie]

High school junior Kayla and her two best friends have always been close. Even after Kayla becomes a cheerleader with a basketball star boyfriend, Riley falls in with the skaters, and Evan loses himself in school, the three remain dedicated to their promise to each other: to remain friends no matter what. But when a disastrous prom ends with Kayla single and her best friends dating, the strength of their bond will be tested. Because, as Kayla soon realizes, her feelings for Riley are more than just friendly. Dating a girl is something that’s never crossed her mind before, but more than that, she can’t bring herself to hurt Evan. As tension between the two girls grows, Kayla is forced to grapple with the fact that she might be bisexual, in love with Riley, and about to break their friendship apart.
