Hawk Quest by Robert Lyndon
The Normans have captured England. The Turks have captured a Norman knight.
And in order to free him, a Frank warrior named Vallon must capture four rare hawks.
In the company of a Sicilian scholar and an English falconer, Vallon sets off a heart-stopping odyssey to the far ends of the earth - from Greenland to Russia to Constantinople, across raging Arctic seas and blood-drenched battlefields. Braving Viking warlords, vengeful Normans, and the unforgiving elements, Vallon and his comrades must track down their quarry one by one in a relentless race against time.
Ten years in the making, Hawk Quest is high adventure in the grand tradition of Bernard Cornwell and Robyn Young, an epic story packed with visceral combat, marvellous period detail, and gripping suspense.
The scale is huge.
The journey is incredible.
The history is real.
