philosophical books discussing purpose of life, inevitability of death etc for a beginner who is just dipping toes in this genre

I want to start reading such type of books which inspire me to think and ponder and question. I want mind boggling philosophical concepts or theories which make me go, “Wow, that’s something that I have never thought of.”

I want something that talks about life and how weird and transient it is. I want to talk about how one can figure out their purpose in life. I want to learn about death and all the morbidities. Please suggest me such books but also as I am beginner, I wouldn’t want something too complicated.
