'While on a ghost tour in Castle Crioch, Sophy and her best friend and foster sister, Aria, are sucked into the world of Argenterra, where they encounter a strange Crystal Tree. Two leaves fall from it, one of which Aria catches and the other mysteriously delves into Sophy’s chest.
'Met by Dellbright, the prince of Valley Keep, and Oakheart, the high king’s ambassador, the girls learn they are expected. Aria has beauty and talent with the given, the land’s native magic. She finds a home and a husband in Prince Dellbright and is revered as the legendary Gift of Crystal Tree Woods.
Sophy is out of place as anything made with the given makes her ill.
'Sophy accompanies Oakheart to the capital to find out why the crystal leaf is in her chest. A sinister force is tracking her—trying to snatch her away or kill her. Only Oakheart suspects her importance: she is the talisman that can cause great harm to the world of Argenterra if she falls into the wrong hands.' (Publication summary)
