“…you must realise and accept, neither me, your mum, nor either of you are human.”
 
Nick and Mel are 14 year old twins living normal lives with their parents. When they discover an ancient book in the attic and read from it, strange events begin to happen around them. Something has been awakened which prompts their parents to take them away to a town called Midway where they reveal to the twins that they are not human. They had been hidden on Earth, brought up as though they were human, awaiting the right moment for the truth to be told.
 
When their parents mysteriously disappear on their first night away, they are forced to discover for themselves what their roles are in the new lives they’ve been thrown into. They struggle alone as they try to understand and balance their past human lives with their alien destiny. When the book they discovered at their home is stolen, it falls on the twins to recover it. The book has a lot more power than they realised, and if they fail, it will not be they who suffer, but the whole human race.

Along the way, they meet an array of characters, some will become friends, some will become enemies, who can they trust? For now, they can trust only each other.
