I had bought "Still Alice" by Lisa Genova before Christmas at Coles. I forgot I had bought it. I picked it up last week again and couldn't get through it quick enough. It's a book about a Harvard psych professor who discovers she has early onset Alzheimer's.
I loved this book. I cried a lot while reading it. The story is told from the perspective of Alice, and how she deals with her diagnosis, and then how she thinks when in moments of un-clearness. As the time goes on, her illness progresses, and it is really just heartbreaking to read.
I don't want to say much else about this book in case you haven't read it. Pick it up if you want an emotional book that really pulls you in.
