Book spoiler websites (plot synopsis with spoilers)

I was looking up the ending of a book for my wife bc she’s worried it’s going to be sad (she’s super pregnant and reading “The Great Alone” which is super depressing)

I could NOT find a website that would give me a full synopsis with spoilers and the ending.

I didn’t find it on cliff notes or spark notes, Wikipedia, or even bookspoilers.com

Is there a website that has spoilers and synopsis for newer books?
