The promised lie - Christopher Nuttall

In The Promised Lie, book 1 of The Unwritten Words, Christopher Nuttall weaves a new epic series in the world of his bestselling Bookworm series. Five years have passed since the Golden City fell. The Grand Sorcerer and Court Wizards are dead. The Empire they ruled is nothing more than a memory, a golden age lost in the civil wars as kings and princes battle for supremacy. And only a handful of trained magicians remain alive. Isabella Majuro, Lady Sorceress, is little more than a mercenary, fighting for money in a desperate bid to escape her past. But when Prince Reginald of Andalusia plots the invasion of the Summer Isle, Isabella finds herself dragged into a war against strange magics from before recorded history ... ... And an ancient mystery that may spell the end of the human race.
