As with all great discoveries, Mark Teague's eureka moment materialized from something seemingly unrelated when a move from San Diego to New York City planted the seed for his first picture book, The Trouble with the Johnsons. His debut earned him a feature in Publisher's Weekly as one of eleven prominent new authors of 1989 and secured his place among beloved children's authors. Each of Teague's books starts as “notebooks full of sketches and scribbles, strange little drawings, and phrases that seem mostly cryptic that suddenly come together,” he explains. And though Teague developed his writing and painting talents without formal training, his boundless imagination has earned him a permanent place in the hearts of children. His books tackle common childhood fears — imaginary monsters living in closets, being late for school, or meeting a new baby-sitter. Mark admits that his own daughter was pretty calm in comparison to the Eggmont children in Baby Tamer, but the idea for the book came from her. One Halloween Night sprung from his love for the holiday — the way a costume can give a person a whole new identity and how everything is transformed into something mysterious and spooky.
