The day that Christopher saved a drowning baby griffin from a hidden lake would change his life forever.

Its the day he learned about the Archipelagoa cluster of unmapped islands where magical creatures of every kind have thrived for thousands of years, until now. And its the day he met Malagirl on the run, in desperate need of his help.

Mal and Christopher embark on a wild adventure, racing from island to island, searching for someone who can explain why the magic is fading and why magical creatures are suddenly dying. They consult sphinxes, battle kraken, and negotiate with dragons. But the closer they get to the dark truth of whats happening, the clearer it becomes: no one else can fix this. If the Archipelago is to be saved, Mal and Christopher will have to do it themselves.

Katherine Rundells story crackles and roars with energy and delight. It is brought vividly to life with more than 60 illustrations, including a map and a bestiary of magical creatures.
