    In fact, five of them could fit into the period at the end of this sentence.On a clear, warm Sunday, April 14, 1935, a wild wind whipped up millions upon millions of these specks of dust to form a duster—a savage storm—on America's high southern plains.The sky turned black, sand-filled winds scoured the paint off houses and cars, trains derailed, and electricity coursed through the air. Sand and dirt fell like snow—people got lost in the gloom and suffocated . . . and that was just the beginning.Don Brown brings the Dirty Thirties to life with kinetic, highly saturated, and lively artwork in this graphic novel of one of America's most catastrophic natural events: the Dust Bowl.

    One event in 1934 - the shooting at Uluru of Aboriginal man Yokunnuna by white policeman Bill McKinnon, and subsequent Commonwealth inquiry - stood out as a mirror of racial politics in the Northern Territory at the time.But then, through speaking with the families of both killer and victim, McKenna unearthed new evidence that transformed the historical record and the meaning of the event for today. As he explains, 'Every thread of the story connected to the present in surprising ways.' In a sequence of powerful revelations, McKenna explores what truth-telling and reconciliation look like in practice.Return to Uluru brings a cold case to life.

    A funny and frank look at the way Australia used to be - and just how far we have come. "It was simpler time". We had more fun back then". "Everyone could afford a house". There's plenty of nostalgia right now for the Australia of the past, but what was it really like? In The Land Before Avocado, Richard Glover takes a journey to an almost unrecognisable Australia. It's a vivid portrait of a quite peculiar land: a place that is scary and weird, dangerous and incomprehensible, and, now and then, surprisingly appealing. It's the Australia of his childhood. The Australia of the late '60s and early '70s. Let's break the news now: they didn't have avocado. It's a place of funny clothing and food that was appalling, but amusingly so. It also the land of staggeringly awful attitudes - often enshrined in law - towards anybody who didn't fit in. The Land Before Avocado will make you laugh and cry, be angry and inspired. And leave you wondering how bizarre things were, not so long ago. Most of all it will make you realise how far we've come - and how much further we can go.
