Sorry, no use. I have de-active a snip plugin. But it still there.

Which post is deleted?

The Holistic Beauty Book.

Where is that book on your website? I can’t find it.

if you click on any of existing post, you would see the Holistic Beauty Book at bottom of the post ie (you may like…)

Is that “You may also like” stuff from a plugin?

The only plugin is All In One Schema.org Rich Snippets. I ready de-active it. I click on The Holistic Beauty Book, it brought me home page. I have deleted Holistic Beauty Book cover, I don’t know why this still happen.
