The World Fixers - Book 1 - the Blue Boy and the Red Princess

"In a land called Cora, live two teenagers who unwittingly hold the future of the world in their hands. Their names are Andrew and Heidi. They are bitter enemies. When Andrew’s father goes missing after discovering an ancient book of secrets which contains a map that promises peace if followed, Andrew becomes desperate to find him. But following the map is a dangerous journey that begins in the enemy’s capitol — only a fool would attempt such a dangerous undertaking. So begins a whimsical yet very serious morality tale full of wild adventure and critical life lessons that mirror the challenges we all face today in a deeply divided world." -- Description from author's website.
