Wells-reference alert!) and her husband, a lifelong dilettante named Shaw, move their two young kids from Manhattan to the woods of upstate New York so he can pursue his new passion for painting.

Did you know?

Knowing that minatory means "threatening," can you take a guess at a related word? If you're familiar with mythology, perhaps you guessed Minotaur, the name of the bull-headed, people-eating monster of Crete. Minotaur is a good guess, but as terrifying as the monster sounds, its name isn't related to minatory. The relative we're searching for is actually menace. Minatory and menace both come from derivatives of the Latin verb minari, which means "to threaten." Minatory was borrowed directly from Late Latin minatorius. Menace came to English via Anglo-French manace, menace, which came from Latin minac-, minax, meaning "threatening."
