Touch of Kindness - R. Loomis - Bog

Dori Livingston doesn't want to be anything special. She's fine staying in the background, helping her friends, and supporting her single mom in any way she can while living in her small Texas town. That all changes when she meets a strange girl at school who is running away. In true Dori fashion, she welcomes the girl into her home without hesitation. Little does Dori know that helping this girl will spark a chain of events that will change her life forever.
After showing Dori her ability to influence people with a single touch, Dori is left with more questions than answers. The next day, Dori is captured and taken to the Otherworld, a place full of magic and fantastical creatures. She learns the girl she helped was betrothed to a prince, and now Dori must fill the void and marry His Highness in the girl's stead. Dori's mission becomes clear: get back home no matter what. However, getting back to the Mortalworld will be harder than she could have ever expected.
