The Witch Family — Eleanor Estes

This story of two girls trying to banish a witch is “full of wonderful fun, excitement, and humor” (Library Journal).
 
Old Witch likes nothing better than to fly around on her broomstick, crying “Heh-heh!” and casting abracadabras. But now she has been sent away . . . by two young girls.
 
Amy and Clarissa have decided that Old Witch is just too mean and wicked. So, drawing a rickety old house upon a barren glass hill, they exile Old Witch there with a warning: She better be good, or else no Halloween! But to give Old Witch some company, they draw her a Little Witch Girl and a Weeny Witch Baby . . .
 
Old Witch tries to be good, but anyone would get up to no good in a place as lonely as the glass hill. And Amy and Clarissa are about to find that out, when Old Witch magics them into her world of make-believe-made-real, in “a very special book that is certain to give boundless pleasure -- at any time of the year” (The Horn Book).
 
“A classic for Halloween.” -- Library Journal
