Good Cliffhanger for this Story?

that sounds like it could be really amazing, to get a finishing sentence you should create a strong sentence near the beginning, you could even use the opening sentence and use it at the end too. it should be either really complex and moving, or short and simple. maybe even a question, something that rounds your story off neatly, but still leaves the reader in suspense. you could even turn the sentence into a sort of motif, as i did with one of my previous pieces (i used the words "I am content." throughout, and finished with the slight variation "we are content.")
