I’m having trouble locating a children’s book. Here’s everything I remember:
Picture Book
I first read it in the late 90s so definitely published before 2000
A girl ends up in heaven/utopia for 3 days and when she returns to her mom 30 years have actually passed. Her mom has aged significantly.
She might have been fleeing from a war.
That is all I remember and I am completely stumped. Hoping you can help since google was unable to.
Dear Mili, by Wilhelm Grimm, illustrated by Mayrice Sendak.
