Okay so December has been a month of A Song of Ice & Fire by George RR Martin.
Book 2 - A Clash of Kings
Book 3 - Part 1 - A Storm of Swords : Steel & Snow
Part 2 - A Storm of Swords : Blood & Gold
Book 4 - A Feast for Crows (I'm halfway through this one.)
All of these get 5 out of 5... I can't put them down.. its completely book heaven.. and with my Christmas vouchers I bought the huge 1000 page Book 5 A Dance with Dragons. Alas he hasn't finished writing Book 6 yet.... he needs to write faster!!!
