What do you call those text at the back of the book cover whereby they give a sypnosis or brief summary?

Epilogue, index, colophon author's note, bibliography, lots of other stuff can be at the back of a book.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
