Essential Self-Defense by Adam Rapp
In Essential Self-Defense, disgruntled misfit Yul Carroll takes a job as an attack dummy in a women's self-defence class and finds himself mysteriously drawn to Sadie, the repressed bookworm mercilessly honing her skills on him. Meanwhile, alls not well on the unassuming Midwestern streets of Bloggs: with local children vanishing at an alarming rate, our hero, his lady friend, and a motley assortment of poets, butchers, and punk librarians prepare to battle the darkness on the edge of town.
