Today sees the unveiling of a memorial to RAF Bomber Command. To mark this long awaited occasion, we are discounting our Aviation series for a short period of time.

For today and tomorrow, the ACE, AEU and COM series will be discounted by 25% (the books will be discounted when placed in your basket - don't be dismayed if the price on the store page hasn't yet been reduced).

For more information, visit the Daily Telegraph for a live feed of the Memorial Service.
