Jewel on Sapphire

Life on the space station Sapphire is never dull!
Mia Rey's biggest worry is how to collect money for the school fundraiser, until she finds an alien hiding on the station! Her parents never wanted a pet, but she loves the little creature at first sight.
When it starts getting sick, however, keeping the alien hidden becomes the least of her problems. Not only that, but the alien is destroying her room! Can she figure out what's wrong before it's too late? And can she show her parents that she can care for a pet on her own?
