City of Ruin

In a world of monsters, bombs fall on the city's destroying all of humankind leaving only Faykin, Drakus, Demonkin and Darklings.
Feykin, the vampires, mages and shapeshifters of times long gone.
Drakus, the hill giants, orcs and orgers.
Demonkin the dark creatures of demonic bloodlines.
But the Darkling, known as Queensbloods, Kingsbloods, and Elemental tuners can change the fate of the world, with a drop of their blood they can enchant entire theatres, command hundreds of armies and even kill with only a word.
...
Scarlet lost Ruin in the rush, now in the desolate calm that came after she found half-vampire sisters Hazel and Meadow and the shapeshifter Gideon. Ruin found Ashe nearly dead when the bombs fell.
As the two groups flee towards Andreas they are challenged along the way, with what they know and what they hope to find there.
