The Dragoneer, Paperback

High school is hard enough without a dragon breathing down your neck. When 15-year-old Moira Noble stumbles across a cave and a dragon in need of her help, she unwittingly forms a link to it and becomes a Dragoneer. Now the growing Zephyr needs a new place to stay and a steady supply of spicy potato chips.

Moira's homework now includes learning how to use magic and fight with a sword, so that she can keep Zephyr safe from an escalating troll threat. In the meantime she must keep up appearances at school and at home--because if she fails to help Zephyr find a way home, it won't just be the life of her dragon on the line...but hers as well.
