'Providence' is a warship. Probably sentient, but best not to think about that too much. Better for its crew to pretend they're not just passengers chosen for their media-friendly back stories: hunky warrior, adorable geek, stoic captain, bubbly propagandist. In this war against the aliens known as 'salamanders', the four humans dutifully take to their stations—Weapons, Intel, Command, Life—when the enemy is engaged but, again, best not to get in the way. Then, half way through a four year tour, closing in on 600,000 kills, the salamander hits the fan and the four crew members have to dig deep to find strengths they definitely weren't recruited for. Max Barry is a successful Australian sci-fi writer, so quite a rare breed. I didn't love this book, but I celebrate the Max Barrys of Australian fiction.
