Protagonists

• Kylie Galen is the protagonist of the Shadow Falls series. She has always felt that she didn't belong, but she never imagined how much. When her mother sends her to Shadow Falls Camp, she learns that the place is not filled with troubled teens as she's told, but with supernatural creatures: vampires, werewolves, fairies, shape-shifters, and witches. The problem is, she is one of them, but no one knows what she is, and her quest to find out begins. But problems don't stop coming from there - she is constantly followed by a certain spirit that only she can see, her heart is tormented by her parting family and two guys who have a strong affection on her; the handsome and generous Derek who shares her feelings, and the hotheaded werewolf Lucas, who shares a secret past with her.
  Throughout the series, she develops multiple special powers, such as "dreamscaping", superhuman speed, superhuman strength, and healing that only comes when she wishes to protect others. At the end of Taken at Dusk, she finds out that her species is called "chameleon": a hybrid that acquires abilities from several species passed down through the generations. In Whispers at Moonrise, she begins to show brain patterns and abilities of witches, vampires, fae and werewolves, respectively. At the end of Whispers at Moonrise, she leaves Shadow Falls to live with her grandfather. In Chosen at Nightfall, Kylie returns to Shadow Falls and discovers an enchanted sword to aid her in an upcoming battle against Mario. She searches in her heart and finally realizes her true feelings for Lucas. At the end of the novel, she confesses those feelings and successfully defeats Mario as well as his son John on the mission to save her mother while also ensures the acknowledgement of chameleons to the open world.

• Derek Lakes is one of Kylie's two love interests in the storyline. He is a half-fae with power to sense/control emotions, erase memories, dreamscape and communicate with animals. Because his father left him at an early age, he formed a deep dislike to his hereditary powers. In the beginning of Born at Midnight, he attends Shadow Falls Camp solely to learn how to give up these abilities, but when he uses them to save the camp and Kylie, he finally learns the benefits of having them and openly embraces them. He has a strong connection with Kylie, but her affection towards Lucas and his ability to sense a powered-up version of her emotions put them at a distance. Near the end of Awake at Dawn, he leaves the camp to go on missions for the FRU (Fallen Research Unit), but returns in Taken at Dusk with ex-girlfriend, Ellie Mason, whom he confesses to having slept with when they reunited. At the end of Taken at Dusk, he confesses his love to Kylie and maintains as her friend in Whispers at Moonrise. In Chosen at Nightfall, he tries to get close to Kylie again, but she turns him down, saying they both had moved on. From then on, the two become friends officially.

  In Awake at Dawn, he is occasionally visited by Kylie in his dreams before his return to Shadow Falls, and saves her from a rogue vampire's capture. They begin a relationship sometime after Derek left the camp, but things become complicated when his pack and family refuse to let him be with someone not of their own kind. This very problem causes a rift between the two as Lucas himself wishes for Kylie to be a werewolf. He eventually finds out that she is a chameleon, but continues his relationship with her, saying that he loves her too much to let her go. At the end of Whispers at Moonrise, Kylie finds out that he is engaged to another werewolf in hopes of getting his father's vote to join the Werewolf Council and breaks off their relationship. In Chosen at Nightfall, Lucas gives up everything to win back her trust and affection. He also assigns himself to teach Kylie how to fight with a sword after a magical crusader sword appeared to her, and finds a way to join the Council without having to go through marriage.
