The Night Journey is a 1981 novel by Kathryn Lasky.
[1] Nana Sashie (an Ashkenazi Jewish woman born in Mykolaiv in what is now Ukraine) tells her great-grandchild, Rachel, of her escape from the Russian Empire during the early 1900s, when pogroms were common.
Nana Sashie refuses to eat for a week with the intention of dying, and passes away.
Before moving to Minnesota, Nana Sashie was married to Reuven Bloom for 40 years.
Open Court Reading took the book and shortened it, giving Rachel the name "Rache".
