Recommend me some novels about the London Blitz?

Like it says in the subject. Can you recommend me any novels set during the Blitz in London and around Britain? So far I've just read "To Say Nothing About The Dog" by Connie Willis (ok, I guess that was Coventry and not London) (and her new book "Blackout" is also on my list), and "Full Dark House" by Christopher Fowler. And Narnia, I suppose. Also I really liked "The Stolen Child" and "The Doctor Dances" episodes of Doctor Who, though obviously that's not a book. I think it's a very interesting time period, and I am trying to learn more about history

Any suggestions? Thanks in advance!

PS If there are some really obvious books, please point them out as I am clueless!

Sounds just right! Keep em coming!
