I've read the game of throne books (A song of Ice and Fire). The first tv series was okay, but it's been getting further from the books since. I've not seen the current season yet. I didn't mind the books.

I really can't pick a favourite book...

The first full book I read by myself was Black Beauty, so that's got a special place for me... I've had to buy a few copies since, I keep reading them to pieces. 😛
I love the Black Magician Triliogy (and the prequel and sequel series) by Trudi Canavan. Aussie writer too. 😄
