I might be a it late with this but there is a Winter Stacks Challenge being promoted by Overdue Books going on at the moment encouraging readers to choose five books from their shelves that they will read over winter. In terms of working out where you go next in terms of book choices it is a great motivator. So these are my choices, some classics in there that I should have read before now:
James Joyce Ulysses
Gabriel Garcia Marquez Love in the Time of Cholera
John Steinbeck East of Eden
Mikhail Bulgakov The White Guard
Nikolai Gogol Tara Bulba
