Ember

"The most powerful weapon on Earth is a human soul on fire." -Ferdinand Foch

Ember doesn't quite know what's wrong with her. With her parents dead, her house burned down, and a mysterious man following her, she has no choice but to turn herself over to social services. But after 5 years in an orphanage, a strange girl shows up and pulls her away to a beautiful but broken oasis, and the secrets that have been hidden from Ember her whole life come back clambering for her attention. In a huge clash of the elements, Ember's forced to find herself before evil takes her over entirely. {Book one in The Esoterics series}
