Middle school presents a new kind of challenge for Sam and Ally, but also a chance to make a unique friend. When one of their teachers needs help, the three of them come together to lend her support. Nestled in the woods that surround their homes is Covington Ranch. An abandoned estate once used to raise famous horses, a family tragedy has left it forgotten and neglected. But someone has come back. What does their teacher, a rich stockbroker, and a stolen ruby called The Eye of Jupiter all have in common? Sam and Ally vow to find out, and in doing so, start a chain reaction. It could either have dire consequences for those involved, or bring a broken family back together again.
