The Damask Circle, tome 2 : Circle of Death
Keri Arthur2014

In one vicious night, Kirby Brown's world is torn apart. Her best friend is dead, killed by a madman who is now after Kirby, and she has no idea why. When the police prove incapable of protecting Kirby, she has no choice but to trust a mysterious stranger. And while she finds herself inexplicably drawn to him, she fears the strange abilities he wields. An investigator for the Damask Circle, Doyle Fitzgerald, has come to Melbourne, Australia, to hunt down a killer. What he doesn't expect to find is a cadre of witches capable of controlling the elements, a sorceress determined to take that power for herself, and a broken woman who is more than she seems. Doyle is certain that the reason behind the bloodshed lies in Kirby's past--a past she has no wish to remember. Because Doyle isn't the only one with magic in his soul: Kirby's special gifts have the strength to destroy the world.
