From the bestselling author of The Grandest Bookshop in the World comes the third instalment of an epic fantasy adventure series in the tradition of Skandar and Percy Jackson.

Having found two parts of the legendary Oceanforged Armour, Cori, Tarn and Jem set sail to find the third in Halcyon, the secretive island once famed for its beauty. But now that the Prime Council knows of their quest, the journey is more dangerous than ever.

In Halcyon, Cori and her friends are shocked to discover how much has changed since the Age of Glory. The island’s cruel and unpredictable leader forbids all magic in the region except his own. His word is law – and obeying the law has never been Cori’s strong point …

The adventure continues in the action-packed third instalment of the Oceanforged series, from the bestselling author of The Grandest Bookshop in the World.
