It's a sci - fi novel set in 2540. That's basically all I can give you about the plot. You said it was set in London, didn't you? So rather than thinking of it as a boring book set no where near your time in a foreign country, think of it as a book for people with different preferences to you just down the road from me.
After you've finished reading a chapter or two, close your eyes and imagine me as an old woman looking at that situation. Life expectancies are always being lengthened. I might be alive in 5 hundred and something years, who knows??
Ps just pick a different genre next time, ok Ben?
