1. Mystery Horse at Oak Lane Stable
    Meet Cassie Piotrowski -- a hard worker, good student, and devoted horse lover. Her dream of owning a show horse comes true when her dad gets an unexpected promotion at work in spite of the nation's economic hardships at the end of the Vietnam War. But things don't go quite like she hopes . . . Despite being in the middle of horse craziness, Cassie will spend the summer between 7th and 8th grade facing unexpected growing pains: a secret crush disappointment, a challenging friendship with one of her long-time best friends, and learning that life isn't always fair -- she may not get what she wants, but she will end up with exactly what she needs.
