Alaska Troi is a girl on the streets, an orphan seperated from her brother. When a chance encounter with and alien who calls himself the Doctor surfaces, as does the chance to travel with him, she leaps at the chance. Through their travels, however, Alaska will discover that there are hidden secrets that surround her, and that she must find a way to unlock them.

Having lived in an orphanage in Scotland all her life, young Lynnie Wilhem doesn't have the best life. Just dull and depressing. Until a strange woman gives her a time-travelling watch. Until she meets a man. A man with a box. A man who, like her, is just travelling.
