The sweet far thing - Libba Bray

It has been a year of change since Gemma Doyle arrived at the foreboding Spence Academy. Having bound the wild, dark magic of the realms to her, Gemma has forged unlikely and unsuspected new alliances both with the headstrong Felicity and timid Ann, Kartik, the exotic young man whose companionship is forbidden, and the fearsome creatures of the realms. Now, as Gemma approaches her London debut, the time has come to test those bonds.
As her friendship with Felicity and Ann faces its gravest trial, and with the Order grappling for control of the realms, Gemma is compelled to decide once and for all which path she is meant to take.
Pulled forward by fate, the destiny Gemma faces threatens to set chaos loose, not only in the realms, but also upon the rigid Victorian society whose rules Gemma has both defied and followed. Where does Gemma really belong? And will she, can she, survive?
