The first in the series, The Secret of Blackwatch introduces 11-year old Maggie to the reader following the death of her mother. Maggie dreams of owning her own pony as her mother did before her death. Her dream comes true when her father surprises her with a trip into the mysterious world of Blackwatch Stables. Lead by the scrupulous Ms. Cavalieri, Maggie learns that owning a pony is a bit different than she imagined. Guided by the other girls at the barn, she learns that caring for her pony, Bella, is hard but rewarding work. As her adventures at Blackwatch Stables begin, she and Bella quickly develop a magical relationship full of love and trust that carry them through an extraordinary adventure.

The Secret of the New Rider quickly drags readers back into the mystery and magic of Blackwatch Stables with changes at the barn that no one – not even Ms. Cavalieri – saw coming. Rumors of a new rider create excitement among the girls but also introduce new challenges, and the growing tension with Stephen and his dragons tests their courage and strength. In the midst of these changes and challenges, Maggie and Bella together must cope with the memories of Dragon Mountain and with the consequences of a mysterious birthday present Maggie receives. Adventure, mystery, and friendships new and old provide comfort, guidance, and phenomenal entertainment for all as the story of Blackwatch Stables continues to unfold.
