What was the first book that made you cry?

I‘ve never been an avid reader and only read like 10 to 15 books a year. So far there’s only one book that ever made me cry: 11/22/63 by Stephen King.

This book is also the longest I’ve read so far which might be one of the reasons I was so invested in the plot. The climax and the ending eventually made me cry. I’ve never had such a feeling before while reading but I hope to find more books that have the same effect.

What was your first or only book that made you cry?
