Sorcha's heart is broken. Even though she's home with her family, she can't shake the memories of her time in Guy-Brazil. She heals with a heavy heart, tells stories with melancholy in her words and cannot forget about the magic of the Other World. When she has a chance to return to her beloved fairy prince, she agrees to the deal. Dark magic, druid curses, and a portal opened by a witch send her to the Otherworld, where she finds herself in the middle of a war she must end.

Saving the fae is not easy when she has become the one they fear. The exiled king makes his way, freeing the lower fairies with swings of his sword. Eamonn becomes more monstrous with each attack. The crystals prevent him from moving and harden his heart. Together they will stand against the Seelie king and his golden army in a war that will change the fate of the Otherworld forever.
