2020: Emille Semner is neither a hero nor a villain. She's a decent student, a good daughter, and a lover of books. That's why, when she spies a spellbook hidden in the depths of the university library and steals it, she is shocked to her core. As strange things start happening and the secrets of the journal begin to reveal themselves to her, she is forced to answer one unrelenting question: is there any story in which the sidekick rather than the superhero saves the day? 1873: Arthur Coleman despises Lillabet Simmons. Or rather, he'd love to despise her. The sting of their last meeting has followed him across states, through time, and into his little cabin in the woods. So when he receives a letter from her, he can do nothing but respond. He couldn't have guessed that this final letter and their following meeting would be the beginning of his end. But had he known, he probably would have written it anyways. Because if there is one person he's willing to be destroyed for, it's Lillabet.
