'Robyn Young realistically evokes the brutal world of the late fifteenth century, and interweaves a gripping tale with a highly original take on Richard III and the Princes in the Tower. Provocative and grounded upon impressive research, this is historical fiction of a high calibre. More, please!' Alison Weir

1483: A secret war is born...

Jack Wynter is trapped in sun-baked Seville, sent there by his father with a locked box he's been told to guard with his life. A vital task, or just a ruse to get an illegitimate son out of the country?

But, then, when his father is arrested for treason, Jack finds himself at the heart of a deadly conspiracy.

Seeking answers to the mystery he has inherited, Jack returns to England, where his half-brother, Harry, broods bitterly over their father's apparent preference for a bastard son and young Prince Edward is due to become king... unless his uncle, Richard of Gloucester, makes a play for the throne.

Jack Wynter is coming home, to a realm of danger, intrigue and war. Somehow, he is connected to a secret that stretches across Europe, and beyond. A secret with the power to kill him - or make him.

Sons of the Blood is the first in an epic new series from the Sunday Times bestselling author. Look out for part two, Court of Wolves.
