One humid afternoon at Malfoy Manor, Narcissa sees something which triggers some powerful memories.
Early one morning in his final year at school, Harry reflects on how he and Ron went from best friends to something more.
When Harry and Draco first met in Madam Malkin's robe shop, neither ``of them could have anticipated how much loathing and mistrust would follow. But ``one day in their fifth year something happens which forces Harry and Draco to ``reconsider exactly what such abhorrence is founded on. Little by little, each ``of them is overwhelmed by Unthinkable Thoughts, and they begin the voyage that ``takes them from their safe harbours of deep suspicion well out into uncharted ``waters. And the more they discover, the more the realise that things can never ``be the same again!
