@comics #comics Did anyone else collect or read these Dial H comics from 2012-2013? On a re-read I still think they're pretty great fun, with #ChinaMieville 's brain fizzing away at inventing absurd new heroes, brought to life by #mateussantolouco and […]

That's an absurdly impressive list of authors giving cover blurbs - Alan Moore, Samantha Shannon, and Adrian Tchaikovsky! A body-warping plague escapes from thawing Siberian permafrost and changes how a series of narrators experience death and loss, with each […]

Just finished reading The Lord of the Rings with my son. He enjoyed it a lot, which is in contrast to the first time a few years back that he attempted it and found it too heavy going, and rearranged the book spines to record his review! @bookstodon
A box of seven Lord of the Rings books (two volumes for each book, plus one of extra material), with the spines each displaying one letter of the name TOLKIEN. They have been rearranged to spell NOT LIKE.

King Arthur's life story is told across 4 novellas published between the 1930s-50s, collected in one volume here. The first half stands with the most fun I've had with a book in hand: startlingly hilarious and studded with bizarre passages like the full page […]

Holy crap! The drama. A penalty goal awarded as time expires. Brisbane have tied it up 28-28. Extra time. They were 28-12 down and looked dead and buried.

For those who felt that youth radio station #triplej 's #hottest100 of Australian songs vote was taken over by millennials, they've released the top 20 as voted by 18-29 year olds and it's not very different, although Untouched does climb to number 1 […]

@scifi Finished the July/August issue of #asimovssciencefiction magazine. A bit of a rollercoaster of quality this issue, with the low point a story by Dominica Phetteplace that I found remarkably clumsily written. But, more importantly, very high high points: #richlarson with a story that […]
