From the moment I saw the hardback cover with its three simulated bullet holes, and opened it up to find a map and a timeline of the First World War, I knew this would be a good read and I wasn't disappointed. It reminded me of the boys adventure novels I used to read as a child, though updated for a generation who play computer games and can easily make the mental leap from mobile phones to mobile phones that allow you to time travel.
Jack and his best friend Angus attend a school that turns out to be a front for something different. Nothing new there, but it's not long before Jack and Angus find themselves transported back in time a matter of days before the assassination of Archduke Franz Ferdinand of Austria and his wife Sophie - an event that led directly to the First World War. The two friends find themselves drawn closer and closer to the place it will happen, as they are manipulated by players in both sides of an argument. One side wants to change history by preventing the assassination; the other wants to protect the present day from changing at all. Jack knows he is a pawn in both sides' plans, after discovering that his father is the one who wants to change history. But ultimately, it is for Jack and Angus to decide what to do - do they protect the future, even though millions of innocent people will suffer, or do they intervene and risk the unknown consequences, be they better or worse.
It's no exaggeration to say that in this ingenious story, author Johnny O'Brien really does bring history to life - life and, indeed, death. There is great poignancy about the story, and it not only makes you think about the responsibility of choices, but it takes you back to a time (the time before the two Great Wars) most people today know nothing about. There is a great moment, for example when Jack is surprised to discover a German aboard a British battleship - but then, of course, nobody would have though that was strange.
If you're still wondering, may I say that if ever there was a book to take a chance on, this is it. Expect it to win awards, it's that good.
