About a Boy: Nick Hornby

Marcus knew he was weird, and that part of the reason he was weird was because his mum, not that long parted from his dad, was weird. But he could live with that - and with having the wrong hair, the wrong clothes and the complete lack of cool. Until his mum started crying before breakfast.
She often cried, but morning crying was something new, and it was a bad, bad sign. Enter Will, 36, the coolest of the cool and a determinedly child-free zone. Until he discovered a world of bright, attractive available women, thousands of them. Single mothers.
So Marcus and Will meet, each, obviously, with a lot to learn about living in the nineties.
