Becca Daniels needs a passing math grade...but what she wants is to spend more time with Toby Michaels. The only problem is Toby is her best friend's twin, and Tori has a very firm "no dating the brother" policy. But Becca's grade has hit rock bottom and she needs a tutor. It just so happens that Toby is a math genius and more than happy to help-lucky her! Working so closely with the handsome, popular Toby, Becca can't hide her attraction, and it soon becomes obvious he feels the same way. Becca doesn't want to lose her best friend, but she isn't willing to give up Toby either. At first, sneaking around is fun, stealing kisses right under Tori's nose. But things take an ugly turn when Toby's ex-girlfriend Meredith catches them together. Meredith demands Toby take her back and restore her reputation, or she'll tell Tori their secret. Do they dare tell Tori the truth? Or would that just make things worse? Surrounded by secrets and knee-deep in deception, something has to give... How far is Meredith willing to go to keep Toby and Becca apart? And how much is Becca willing to risk to keep... Our Little Secret?
