That's how history works. Old stories get retold because each (serious) book does new analysis and finds new data which needs reconsidering. And the audience changes, and stories are always told to a specific audience. And in this case, there's always the chance of new official records being released.
Just another popular book on a topic like this isn't needed (whatever needed means), but a new serious analysis, asking perhaps different questions, could well add to our knowledge.
There's also the case that the WW2 bombing campaign is a bit of a troublesome spot in British memory, and so is returned to in a way that might seem on the verge of the obsessional to others.
