The Sweet Far Thing by: Libba Bray (3rd in series)

This book is sooo good!!! I could not put it down and when I had to, I freaked out!

It has been a year of change since Gemma Doyle arrived at the foreboding Spence Academy. Her mother murdered, her father a laudanum addict, Gemma has relied on an unsuspected strength to turn catty schoolgirls into loyal friends, and has discovered an ability to travel to an enchanted world called the realms, where dark magic runs wild. Despite certain peril, Gemma has bound the magic to herself and forged unlikely new alliances with headstrong Felicity and timid Ann; with Kartik, an exotic young Indian man whose companionship is forbidden; and with the fearsome creatures of the realms. Now, as Gemma approaches her London debut, the time has come to test these bonds.

Rule-breaking Felicity must do as she's told or risk losing her inheritance, and Ann's dream of a life onstage slips away. The Order, the mysterious group Gemma's mother was once part of, is grappling for control of the realms, as are the Rakshana. It is there that the girls meet their adored friend Pippa, who is not the same...or is she? The power to change everything--both in and out of the realms--rests in Gemma's hands.

Pulled forward by fate, the destiny Gemmma 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 belong? And will she, can she, survive?
