The yellow letter arrived on a Saturday, otherwise Henry would have been at school.

The envelope was such a bright, sunny colour, no one would have believed that it contained a bombshell.

Less than 10 minutes after the arrival of the mysterious letter, Henry is on the run with his Auntie Pearl, possibly never to return home.

Henry has a secret. He is twelve, but he hasn't aged a day since the moment he was thrust a hundred years into the future.

Now his secret has put him in danger. His only hope is the protection of the Guardians of the Lost.
