Billi SanGreal is facing her Ordeal. The last test before her initiation. But she hadn't expected this. Not killing a little kid. Billi is destined to follow her father into The Order and protect the masses from the Unholy. From the thousands of evil, tortured souls that prey on humanity.

Still reeling from the death of her best friend, Kay, Billi's thrust back into action when the Templars are called to investigate werewolf activity. But these werewolves are like nothing Bilil's ever seen. They call themselves the Polenitsy: man killers. The ancient warrior women of Eastern Europe, supposedly wiped out centuries ago. But now they've come out of hiding and are on the hunt for a Spring Child - an Oracle powerful enough to blow the volcano at Yellowstone - and start a Fimbulwinter that will wipe out humankind for good. The Templars follow the stolen Spring Child to Russia, and the only people there who can fight the supernatural are the Bogatyrs, longtime enemies of the Templars. To reclaim the Spring Child and save the world, Billi needs to earn the trust of Ivan Romanov, a young Russian soldier whose suspicious of people in general, and of Billi in particular. Dark Goddess is a page-turning, action-packed sequel that spans continents, from England to the Russian underworld and back. This is an adventure of folklore and myth become darkly real. Of the world running out of time. And of Billi SanGreal, the only one who can save it.

Billi’s back. Older, wiser and more deadly than ever… Now eighteen, Billi has settled into her life as a Knights Templar, a London teen by day and ruthless hunter of the Unholy by night. Beside her is Ivan, scion of the Romanov dynasty—wealthy, handsome and devoted to Billi. She has everything she could wish for. And it's all about to be taken away. An ancient evil has risen from the deserts of the Middle East and the only way Billi can stop it is by destroying all she loves. Honour, duty and love are all in deadly conflict. Billi must learn to draw on the darkness within in her own soul, and that to defeat monsters, she must become one herself. For fans of Cassandra Clare and V.E Schwab the Templar Chronicles combine ancient mythology, secret societies and high stakes in a brutally dark world where there is no mercy asked for, and none given.
