Jo can't bear the attitude of peole around the teacher who wants to help but can't face the truth that Jo's half black (not just half-white); Straker, the bully who torments and follows her; and most of all, her mum, who refuses to talk about the past and allow Jo to find out about her real dad. That's why she needs Mit - he takes her to a secret world beyond reality, a place where Jo can decide who she really is.
I quite enjoyed this book. I thought it was very cleverly written and overall an interesting read.
Throughout the book Jo grows as a person but to get there she has to take the secret line. Jo's thoughts and views about the real world are refreshed after her journey and as a reader you feel a sense of pride and support towards her.
It's an easy read that only has 219 pages, which is brilliant when you don't fancy a long book but you still want to read.
