Momentum Books is a digital only publisher, part of Pan MacMillan Australia. They're DRM free and make their works available globally. They've got a small selection of fantasy and science fiction.
I like the DRM free aspect of this publisher, but I think it's also important to point out its global nature. Many justifications for pirating books center around cost and availability. Momentum has priced their books between .99 and 9.99, with most at the 2.99 and 4.99 marks. (Note, that's in Australian Dollars, so you have to factor in your local exchange rate.) Just as importantly, allowing people from anywhere to buy their books means there's no excuse for not buying if they've published something you're interested in.
I became aware of this publisher through an email where they announced a prequel to a high selling series of theirs, Greig Beck's Alex Hunter series.
Here's the synopsis for the prequel:
Alex Hunter – in the mission that turned him from a normal man into the weapon known as the Arcadian – and the elite team of soldiers known as the Hotzone All-Forces Warfare Commandos must enter a hostile country to rescue a defected Chechen researcher from the center of a country at war.
But the HAWCs are not the only ones looking for the rogue scientist and the mysterious package he carries with him. A brutal and relentless killer and his death squad are on the trail too – and they bring a savagery with them Hunter and his team have never witnessed before in modern warfare.
In this stunning prequel to Beneath the Dark Ice, the HAWC team must race the clock to rescue the scientist, prevent the package from falling into the wrong hands … and save the world from a horror that should never have been woken.
