My eyesight's less good now so I buy fewer books. I read plays still, being an active member of an amateur drama group -

I tend to enjoy ambiguity, but not only.
Some books that have impressed me in recent years are:
The Master and Marguerita by Mikhail Bulgakov (a Russian classic from the 20's, banned by Stalin)
If This is a Man by Primo Levy
If on a Winter's Night a Traveller by Italo Calvino
The Quantity Theory of Insanity by Will Self
The Leopard by Guiseppe di Lampedusa
Miss Smilla's Feeling for Snow by Peter Hoeg
Sophie's Choice by William Styron
The Curious Incident of the Dog in the Night-Time by Mark Haddon.
The narrator in the book is a 15-years-old boy suffering from autism. An incredible - and uplifting - insight into a state of mind that most of us cannot imagine. (One of my daughters is a speech therapist who has encountered this mental condition among her pupils).
Among the authors are at least one Nobel prizewinner and a Pullitzer prizewinner. Not all of the books may be currently in print in the USA.
Anyone interested in Russia might enjoy:
Natasha's Dance by Orlando Figes "A Cultural History of Russia". Be prepared for some 725 pages. I found it fascinating.
Already too much. Time to stop.
