The Grim Grotto by Lemony Snicket
Unless you are a slug, a sea anemone, or mildew, you prabably prefer not to be damp. You might also prefer not to read this book, in which the Baudelaire siblings encounter an unpleasant amount of dampness as they descent into the depths of despair, underwater. In fact, the horrors they encounter are too numerous to list, and you wouldn't want me even to mention the worst of it, which includes mushrooms, a desperate search for something lost, a mechanical monster, a distressing message from a lost friend, and tap dancing. As a dedicated author who has pledged to keep recording the depressing story of the Baudelaires, I must continue to delve deep into the cavernous depths of the orphans' lives. You, on the other hand, may delve into some happier book in order to keep your eyes and your spirits from being dampened.
