I can't remember half the books I've read this year so this is just a selection:

Barrytown trilogy (The Commitments, The Snapper and The Van) by Roddy Doyle: Trilogy about a various members of a family living in Dublin. The Commitments is about son Jimmy Jr, and the soul band he sets up, The Snapper is about daughter Sharon dealing with her pregnancy, and The Van is about father Jimmy Sr starting up a chip van with his friend Bimbo. They are all quite humourous, and the film version of the Commitments is one of the best Irish films of all time.

If on a winter's night a traveler by Italo Calvino: An amazing book. Everyone should read it.

Slaughterhouse Five by Kurt Vonnegut: Very strange but brilliant book.

Never Let Me Go by Kazuo Ishiguro: As discussed in one of the book clubs recently, a very moving speculative fiction book which is quite disturbing.

Sandman by Neil Gaiman: Not a novel, but a brilliant graphic novel.

Brideshead Revisited by Evelyn Waugh: Very good book.

The Dictionary of the Khazars by Milorad Pavic: Interesting book. Faux encyclopedia written from three perspectives, Muslim, Jewish and Christian, about the medieval Khazar Empire.

Kraken by China Mieville: Not my favourite mievile book, but quite interesting book about squid theft and a potential apocalypse

Not quite finished but worth mentioning:
Right Ho Jeeves by PG Wodehouse: Classic. Hilarious. Read it. It's available for free on Project Gutenberg.

The Amazing Adventures of kavalier and Clay by Michael Chabon: Quite brilliant.
