Over the years Alex has been coming over to the Brown's house, going on vacation with them, she sees him in school all the time, but he has never said a word to her.
It's not like Keagan hasn't tried, she has! He just ignores her on purpose. One day Keagan decides that she is no longer going to be ignored.
She devises a plan to get Alex to talk to her, and she must find out the reason why he is ignoring her.
