Mary Ellen, Craterean. The Crater School, #3

Like private schools back on Earth, the Crater School is primarily the preserve of the upper and middle classes. But the hinterlands of Mars are very rural. Farming the Red Planet is hard, and families rely on their children to help with the work. What, then, is a farming family to do with a girl like Mary Ellen who seems interested only in books, and who asks questions that her teachers are hard-pressed to answer?Then, one day, a chance event changes Mary Ellen's life.
A famous author on a research trip visits her farm and spots her talent. An offer is made, a fully-paid scholarship to the famous Crater School. It seems like a dream come true. But dreams can easily turn into nightmares.
