Its a fictional book. All I can remember is that it's about a group of friends, who I think meet at university, but I might be wrong, and one of the characters is called Benji/Benny who I think dies.
The first chapter is 'now' after 'benny' has died, about 10 years after the beginning, then the book goes back to when they first met and their journey as friends to get to where they are now.
I thought it was Maeve binchy's circle of friends, but I've just re-read that and it's not.
Thanks all
