Glorious, powerful, magic; a city of twists, turns and tricksters; extraordinary secrets which only one girl can uncover . . . welcome to the world of Arkspire.

Arkspire is a city obsessed by magic. The five Arcanists - a group of all-powerful magicians - have protected the great city for as long as anyone can remember. Within the hustle and bustle of these cobbled streets lives Juniper Bell, a thief who''d do anything for her family - even her unbelievably annoying sister, Elodie.

Then one night, something incredible happens. A mysterious stolen relic (nothing to do with Juni, ahem...) explodes, revealing a mysterious creature, Cinder - who appears to ''bond'' with Juni. The only creatures like that are allegedly dangerous enemies of the Arcanists . . . and it''s not long before they turn their attention to Juni.

Soon Juni, Cinder and everyone she loves are pulled into an extraordinary world of magic, power and prestige - but also grave danger. It seems the world Juni thought she knew is nothing but a lie - and now only Juniper and Cinder can bring it down.

A thrilling adventure and astonishingly illustrated new fantasy series, from the bestselling author of Frostheart.
