I read Dark Matter by Michelle Paver this weekend. Brilliant book.
I've had a love-hate relationship with Michelle Paver's books. She is next to me on the bookshop shelves. You'll sometimes find one of my titles holding up dozens of up her six Ancient Darkness books. But I'll read the Ancient Darkness ones now. There are dozens of them there for a good reason.
Dark Matter follows a 1937 Arctic expedition to Spitsbergen, to four months of sunless darkness, one man left on his own. Except he is not on his own. It's chilling, thrilling and beautifully written.
I think the publisher are pitching it as a young adult/adult book. Either way, it's great.
