Lena Valerian was a dotmîr. She was one of the few remaining royalties of the Nightwalker realm. At the age of seventeen, she was tasked to seek diplomatic solutions to end the century-old war that almost wiped her kind to extinction. Infiltrator Thane was Lena's assigned guardian. She dedicated her life to protect the young royalty against the Citadel, the human council who was hell-bent on killing Nightwalkers. After four years of hiding, Lena and Thane were forced to run for their lives, only to discover that the Citadel was planning something much worse than the cleansing of the Nightwalkers. To stop the council, Lena and Thane embarked on a dangerous journey across the human plane- a quest that brought them the temptations of forbidden love and the lesson that they should never let their guard down.

Emma Woodhouse, aged 20 at the start of the novel, is a young, beautiful, witty, and privileged woman in Regency England. She lives on the fictional estate of Hartfield in Surrey in the village of Highbury with her elderly widowed father, a hypochondriac who is excessively concerned for the health and safety of his loved ones. Emma's friend and only critic is the gentlemanly George Knightley, her neighbour from the adjacent estate of Donwell, and the brother of her elder sister Isabella's husband, John. As the novel opens, Emma has just attended the wedding of Miss Taylor, her best friend and former governess. Having introduced Miss Taylor to her future husband, Mr. Weston, Emma takes credit for their marriage, and decides that she rather likes matchmaking.
