Felix Featherstone has anger issues, is isolated at school, and has a dysfunctional relationship with his father. He is also a 'Sagacitor'.

Not until he receives a note in his exercise book, that is, inviting him to go to Hollow Island - the most beautiful place he will probably ever see. But what is really going on in this 'beautiful place' is for you to guess and for him to find out.
