On the heels of a frightening encounter with her shady boss, single mom, Sophie Tanner, flees into the woods and stumbles upon a red, freestanding door. Hunted by vicious dogs and security guards, she plunges into the mist beyond the open door where the mysterious land of Trell awaits. After nearly drowning in a watery trench, Sophie meets Riler and her motley crew of mercenaries and must rely on them if she hopes to return home to her young son. But only one holds the key home-the Mountain King. The journey is long, fraught with towering trolls, goblin sirens, and labyrinths, and when a dark entity takes a romantic interest in her, Sophie realizes she's in more danger than she thought. Otherworldly dreams plague her as her shadowed past stirs to life. Her sense of self begins to slip away and it seems a handsome fae lord has all the answers, but Sophie will do anything to get home to her son. Even if it means battling her deepest-and possibly inhuman-fears.
