Shadow City — Diana Pharaoh Francis

The world is falling apart. The magical apocalypse has come. Now is the time to guard the covenstead against both raiders and refugees. But Max has been stolen by a powerful demi-god who is determined to force her to find a way to use a magical power she never knew she had -- even if it kills her. Meanwhile, back in Horngate, a Fury is birthing. When the creature breaks free of the fragile bonds that enclose her, her rage will scour the covenstead from the earth.

Max finds herself in the Shadow City, a place of mysteries and magic, where she must battle for her freedom or become a slave to creatures of dreadful greed and power. Back in Horngate, Alexander must swallow his anger and pride if he hopes to defeat the Fury, a creature that no one has ever successfully fought before.

In the end, it will be courage, friendship, faith and loyalty that win the day. Or else so one will live to see tomorrow.
