Which do you follow: your head or your heart?

When Sylvie loses the diamond from her late mother's ring, her best friend, Cherise, insists it's a sign that love is about to enter Sylvie's life. Yeah, right. Sylvie doesn't believe in signs -- she only stargazes through her telescope. But she also knows Cherise won't drop it, so to humor her Sylvie agrees to date the next boy who asks.

Sure enough, a new guy appears in school, and Sylvie's the object of his affection. Maybe Cherise was right after all? But when the sparks don't fly and Cherise thinks Sylvie's just scared, Sylvie ends up confiding in an old friend. Could finding the perfect guy be as rare as catching a shooting star?

Which way should they turn?

The kids have to convince Sacagawea not to give up on her dream. But they don't know what Sacagawea's dream is! Sure, they know that explorers Lewis and Clark mapped a route leading out West...but what does that have to do with the teenage Native American?

Can Abigail and her group find Sacagawea, figure out what her dream is, "and" convince her to stick with it -- all in just two hours?
