This Dark Endeavor
Frankenstein is one of my favorite books and this story is about Victor Frankenstein as a young man, when he still lived with his stern, wealthy parents and a twin brother, Conrad, who falls almost fatally ill. There's also Elizabeth, the girl who was adopted and has lived with them since they were children. Elizabeth serves as more than the love interest, as she has a fierce character of her own. Conrad is a perfect gentleman who treats his brother with love and kindness. Victor and Elizabeth--who loves Conrad as more than a brother--are soon on a quest to create an elixir that might cure Conrad forever, with the aid of the kindly alchemist Dr. Polidori. There are some serious misadventures, a gruesome sacrifice, surprises, and, told from Victor Frankenstein's point-of-view, it's definitely apparent that Victor--jealous of his brother and in love with Elizabeth--is a complicated antihero. There's an unexpected and sinister ending that may lead Victor into becoming the character of the Mary Shelley novel.
