Eleven-year-old Danny has gone missing. Is he dead - or has someone taken him? His older sister, Ellie, is determined to do whatever it takes to help find him...

In a separate world, a world of witches and were-creatures, another girl - Argent - sets out on a perilous adventure when a thief snatches a baby dragon just after its hatching...

If Ellie is to find her brother, she must be like Argent - behave like the other girl would. Follow Argent's way - a spiral way, outside the edges of reality. And just as Argent gets help from the mysterious Lukos, could another outsider - living on the fringes of society - help Ellie in her hunt for her brother?
