What is the plot of the horror novel "Dance of Dark Souls" about? Can anyone help me summarize the entire content of this book without giving a brief introduction to the plot?

A couple who are about to divorce decided to vacation together in Thailand for the last time. The night they checked into a hotel in Phuket, something terrible happened... On the beautiful P Island, they experienced confusion and fear like never before. Who is that mysterious woman? Why does she always dance at night? Frank died inexplicably, and his body was filled with terrifying power? Where did that child who wandered like a soul come from? Why are the cries of women in the middle of the night and the screams of night birds in the woods so desolate? ...Everything is so confusing, holding your heart tightly. The living feel the breath of the dead, and they experience fear, but they don't know the source of this fear. The living people live uneasily like this...

Part One\n

The woman wanted to vomit, so she quickly covered her mouth with her hands. This smell reminded her of the stench of rotten meat, the kind of meat that had rotted for a long time, with a disgusting fishy smell. Could it be that someone brought some animal meat on this plane and the meat was rotten? This is impossible. You will not be able to pass the airport security check. The fat woman resisted vomiting because she was most disgusted with the smell of rotten meat. She was thinking about some random question when suddenly the plane started to tremble.

Part 2\n

As soon as Douya turned around, she saw Li Li and Zhang Lan walking into the restaurant. Douya turned around. The small ivory pendant on the beautiful woman's chest was really fascinating. I just like gadgets like this. You know, this kind of gadget hanging on a woman's chest is noble and delicate. I don't like women who dress themselves up in jewels and jewels to make an already beautiful woman even more charming. Those women look vulgar at first sight!

Part Three\n

The commotion caused by the discovery of a dead body by the swimming pool of the Moon Resort Hotel meant nothing to Li Li, who was still thinking about the problem in the room. Li Li looked at the sleeping Zhang Lan and found a teardrop in the corner of her eye. Li Li picked up a tissue and gently wiped away the tears from the corner of Zhang Lan's eyes. Zhang Lan's face was pale. Li Li looked at her and felt heartache. Thinking of what happened last night, Li Li still felt incredible, but it did happen and he had no way to avoid it.

Part 4\n

I found that Frank was no longer beside me, and I also smelled a strange fragrance. I called his name, but he didn't answer me. I don't think Frank just disappeared while I was asleep, right? I got out of bed and found him in the bathroom. He didn't lock the bathroom door backwards. I pushed the door open and went in. I saw Frank sucking white powder! I actually saw Frank taking drugs! How could I believe that Frank was such a person. In my eyes, drug addicts are the devil in the world. I don't believe that Frank, a well-educated man, can be a drug addict!
