Hey Granny W - we have another member here from Bunbury.
I can empathise with you on Terry's books as they have saved my life too - given me something to cling to when things were at their darkest. And his books also brought me together with my wife Sharlene.
Terry has asked in previous posts he's made and in interviews (due to the fact that he got inundated with well wishes) that people don't contact him about the altzheimers unless they have a cure.
I would suggest that you post your wishes here. Terry does look in on message boards and has even been known to post on some of them. This is the website of his UK publisher and I wouldn't be at all surprised if he looks in here.
Wyrd bið ful āræd.
