Read 'The God Desire' by David Baddiel, having read his 'Jews Don't Count' a little while back. Certainly we're left in no doubt that Baddiel is an atheist, but he does acknowledge how much nicer life would be if there was a God. Something we can all agree on. Another point he made in the book was that he wasn't writing it seeking to change anyone's view, as atheists are unlikely to suddenly start believing by reading his stuff, and believers probably don't come looking to him to have their faith tested.
For me, having been brought up in and around the church, a much trickier book was 'Homo Sapiens' which, as it sticks in my mind, rather simply explained how we seemed to have evolved to invent God(s) to fulfil a need in our lives.
