Reagan, Hazel, and Chloe are perplexed- what could Kendra possibly want from them? But when Kendra arrives, they get their answer. It turns out that Kendra has learned of an 'open secret' that EVERYONE at the school has known about except for her. And that secret is that Hazel and Chloe are stepsisters... and not only that- Reagan is their stepmom!
