Of Blood and Bone by Nora Roberts

Thirteen years ago, a catastrophic pandemic known as The Doom killed billions.

For those left behind, it is a chance to build a new world. But The Doom was no ordinary virus. In some survivors, it awoke strange powers – to heal, to harm, even to predict the future.
Fallon Swift has no memories of the old world – but she is destined to shape this new one. Growing up with her three brothers on a quiet farm, she has been protected from danger by her mother and stepfather.
Now she must leave them, and learn to fight. Because Fallon is not only a powerful ‘Uncanny’ – she also has a pivotal role to play in the bloody battles ahead. A war between good and evil is brewing, and Fallon – young, tough, headstrong – must be ready.
