Precious and the Boo Hag is a children's fairy tale by Patricia C. McKissack and Onawumi Jean Moss with illustrations by Kyrsten Brooker.
[1] The story revolves around Precious, a young girl, who is left home, told by her mother to not let "nothing or nobody" into the house.
Her brother teasingly warns her about Pruella the Boo Hag who can change her shape and will do "most anything" to get inside.
Precious is not sure whether to believe him, but while she is alone the Boo Hag arrives on the back of a storm.
The tricky Boo Hag tries to wheedle her way inside, transforming into a thirsty passerby and then into a neighbor girl, but Precious is able to outwit her.
