Fiction:

A Little Life - challenging to read but exceptional

Sci-fi

Three Body Problem trilogy - forget the Netflix series the books are excellent, in my opinion #2 was the peak.

The Glass Hotel, Station Eleven, Sea of Tranquility - anything by Emily St. John Mandel - hard to place but her distinct writing style transports me.

Non-fiction:

American Moonshot - fine The Path to Power - anything Caro writes is worth reading
