The Broken Land (Book 1 of The Kicasia Chronicles)

The Holloway princes were competitive, yes, over the most stupid things. Jude was musically gifted. He played the guitar and the drums, with the voice of an angel. Cole was athletically gifted. He played football, rugby and hockey. Harrison was academically gifted. He taught himself entire university courses and spoke 8 languages. And, of course, they were all constantly competing for their father's affection, along with the chance to inherit the throne.
When the neighbouring country declares war, their lives change forever. They are forced to leave. They find a girl in the woods, her frightened brown eyes compelling the princes to bring her with them, to save her. The journey, however, would not be easy.
