I read this a few weeks ago (been on holiday so no blogging!) whilst it was very hot, and the novel is based in the scorching summer of 1989 (also the summer I was born) so it was pretty apt. Its a relatively easy read but not mindless, it asks questions, is funny and just manages to shy away from cliche at the end! Certainly worth a look.
Next was The Black Cloud by Fred Hoyle - bought for my brother by his girlfriend, probably because of the same last name (quite rare and we're always local to West Yorkshire). It was brilliant and very original.
