Seattle—and the world—has a new playwright to love. Kelleen Conway Blanchard's Hearts Are Monsters is a little bit Hamlet, a little bit Heathers, and a little bit John Waters, a gallows-humor masterpiece about a nerdy high-school girl trying to solve the mystery of her father's murder (and score with her twin's ultra-jock boyfriend). Though each of the characters is repulsive in some way—the mother is a haughty drunk, the heroine is a resentful nerd, her twin is a snide cheerleader, the boyfriend is a half-witted arsonist, and the gym coach is a Dudley Do-Right—Blanchard's sense of humor and humanity makes them all strangely sympathetic. Hearts Are Monsters is a comedy with deep roots. (Macha Monkey at Rendezvous, 2322 Second Ave, 860-2970, 8 pm, $12–$15, through Nov 20)
