THE FIRST CHALLENGE It's assignment time at Angel Academy, and for aspiring angels Mo and Colin, it's their chance to prove themselves. Colin's cool about the whole thing, which really annoys Mo - she's just GOT to do THE best project the Academy has ever seen. But when she dumps poor Colin and goes it alone, things don't QUITE go according to plan. In the end, Colin ends up with the better project and Mo learns a very important lesson - the importance of friendship and working together.
