I was recommended this book by a family member. I'm going to be honest, this book is really bad. The main character is a Mary Sue type character (she can do everything perfectly, tame horses, etc) and it's like a Harliquin romance novel - because there's so much sex in it. This book was a complete waste of time.
Negative
