When Ainsley's older brother asks for a nearly impossible favor, Ainsley refuses at first, but eventually she finds herself dressed up as and pretending to be her brother, Aiden, and tutoring his best friend, Brendan.

The only problem is that she doesn't like Brendan and her best friend, Zoe does. If Zoe ever finds out that Ainsley is pretending to be Aiden then her best friend won't let her forget it.

Brendan has a secret. He's aware that Aiden has convinced Ainsley to tutor him. He is aware that Zoe has been sabotaging Ainsley's relationships. However, what he feels for Ainsley is far from the surrogate older brother feelings that Aiden is pushing on him.

And now is his chance to get Ainsley to see him as more than her brother's best friend.
