Alex's mother is getting married. She should be happy for her but she's honestly really pissed. 1) because she didn't even know her mom was dating Cole until after he decided to propose. 2) because she recently figured out that Cole has a daughter. 3) because his daughter goes to Alex's school and... well... Alex had a giant crush on her. When Claire and her dad move in with Alex and her mom, Alex has to come to terms with the fact that having a crush on your soon to be stepsister is wrong. But for some reason, she can't keep Claire off her mind. Little does she know, Claire feels the same way about Alex.
