Foreshadowing by Marcus Sedgwick
It is England, 1915. 17 year Alexandra Fox lives a privileged life in Brighton. Her elder brothers are both of age for the war, one wants to be a soldier and the other a doctor and does not want to fight. Their disapproving father is a doctor but only sees the honor his sons must bring to the family by fighting the war. Alexandra wants to become a nurse but discovers she has a terrible gift. She can see the future. Her premonitions show her brutal horrors on the battlefields of the Somme, corpse worms crawling over the faces of soldiers soon to die. And worse, they show her what will happen to Edgar and Tom.

Like the Prophetess Cassandra, who witnessed a different war on the plains of Troy, Alexandra is trapped by her tragic power. Cursed by a fate too awful to bear - for who wants to see the end of their own story...? Alexandra's story leads her to the French battlefields, and the road to High Wood, pursued all the while by a mysterious vision of a raven, mocking and taunting her.

Interestingly told as the chapters count down from 101 to 1, leading more to the countdown to doom. It is told from the point of view of Alexandra as her dreams and visions show her the death of soldiers and eventually her brothers. Unable to help her brother Edgar she is determined to save Tom. So she goes as a volunteer nurse to France and the front. In France, she meets a soldier like herself who can see the deaths of those around him. Together they search for Tom. But will she be able to save Tom or is his fate already decided?

This read very fast and was an interesting twist on the typical teen historical novels. I would read more by him.
