Lexie is very unhappy this Valentine's Day. She can't get anything right, and her hearts all look horrible. In fact, everyone at school seems to be in an extra grumpy mood. When she and her sisters consult her magic Mirror of Ice to find out what's going on, they are transported to Heartland, the home of Cupid herself, which is under attack by a scary monster. When Cupid is captured, the girls must navigate the Maze of Misdirection, pull themselves out of Apathy, and survive against attacking Cruel Crawlies in order to find the Chasm of Broken Hearts and save Cupid. But first, Lexie has to learn to love herself just as she is, otherwise Valentine's will forever be filled with broken hearts.
