The Shining Company by Rosemary Sutcliff
'I saw riders with black eyesockets in glimmering mail where their faces should have been, grey wolfskins catching a bloom of light from the mist and the moon; a shining company indeed, not quite mortal-seeming.' Many years after King Arthur defeated the Saxons, the tribes of Britain are again threatened by invaders. Prosper and his loyal bondsman, Conn, answer the call of King Mynydogg to join a highly skilled army - the Shining Company. Led by the gallant Prince Gorthyrn, the company embark on a perilous but glorious campaign. An epic tale of battles and bravery from the acclaimed historical storyteller, Rosemary Sutcliff.
