| Same thing happened to me...  ok, so it was a David Gemmell book, or two, and there are always loads of characters and all his books are pretty similar...  but I had almost no recollection of what went on, who the characters were, etc. etc. etc...  I read 'em both a year or so ago, picked 'em up again recently...just drew a complete blank.  I dunno, maybe in my case it is just David Gemmell-specific memory loss... 
 Gingko Biloba is supposed to be a good supplement to boost the memory, as I recall.  I am sure some aromatherapy oils are good too, in a sort of localised way - but I can't be arsed to check which ones at this point...  hypnosis can probably be quite useful to retrain the memory too...
