Vigil, the final book in The Firewatcher Chronicles, is officially published today in Australia and New Zealand.

In this, the third of the Chronicles, Christopher faces life in London after D-Day, when Hitler’s dreaded secret weapons – V1 and V2 rockets – blasted the city. But he has his own private challenges too, racing across time to discover the secret of the Roman ring he found in the Thames, and to help his friends uncover an ancient temple. It seems simple enough to slip through time back to Roman London, rally his own ragtag troops through the centuries, and beat his arch-enemy Brother Blowbladder. But mastering the power of the ring is never easy.

Look out for it in your favourite bookshop (they’ll order it for you if they don’t have it) or online store.
