Megan Goes Riding: A Spirit Guide, a Ghost Tiger, and One Scary Mother!: Megan Series, Book 19

Megan is a 13-year-old girl with Supernatural powers. Some of them are still only partially developed and others are working, but she doesn't know how to use them yet.
Her biggest problems for the moment is finding a teacher who can show her how to handle them properly. Another is that she doesn't know anyone who knows anything about supernatural powers.
In fact, her mother is violently against the supernatural, as was her mother before her.
The only people who seem willing to help her are dead, not that that makes any difference to Megan.
She embraces their help with open arms.
In Megan Goes Riding, her friend, Jane, invites her to have free riding lessons on a local farm. Megan is keen to try and to meet the animals, but it doesn't turn out exactly as she had expected.
Her Spirit Guide, Wacinhinsha, explains the experiences that Megan and Jane underwent to her at a meditation session and has a smile at her expense.
