Forgotten book title and authors

[RyanBergarasTeeth]

Starting a thread for Forgotten book titles feel free to add your own and see if anyone can find it. I will start. When i was at schook we had to read a book and all i remember from it was:
The main character is a boy with older parents who are a bit strange but he doesnt know why. He ends up going to an open day at camebridge uni with said weird parents. Something happens i think one of the professors recognises him which is weird as he has never been and he sees a photo of himself but doesnt know how as he was never there. Eventually he confronts his parents who tell him the truth. They had a son who was killed either sickness or an accident so after he died they had his dna cloned and out into an embryo so his mother gave birth to him the clone of the original son.

Have you tried the Book Sleuth boards
on abe co uk ? Read their rules first though.

I think you're right, Polly, thank you! I've just been trawling through the Culture plot summaries, triggering many vague memories. I do recall a solitary human learning about the behemoths' ecosystems and, in the process, of a dreadful plot. That ties in with Look To Windward. The horrid birds are raptor scouts/sentinels, I believe.

MUST NOT start re-reading Banks's entire opus now, or I'll be finishing the last when I breathe my last 😳

@Garlicbest Yes I really like the Culture series but the books do demand a considerable amount of time and attention.
