Last Sword of Power (Stones of Power)

BLOOD KING
The Goths followed a bloodthirsty new leader, one who sought to open the Gates of Hell: Wotan. His immortal power stemmed from human sacrifice and dark sorcery, and no sword could touch him. He rode the winds on a leather-winged steed, while his armies cut a deadly swath across the northern kingdoms. Even death's icy hand could not stop them.
Only Uther Pendragon could save Britannia. To do so he must wield his birthright--Cunobelin's blade, the legendary Sword of Power.
But Uther was chained in Hell, the sword lost in swirling Chaos. All hope lay with the warrior known as Revelation, with the magic of the Sipstrassi Stones, and with Anduine, a blind girl possessed of arcane powers. Only if these unlikely allies united could they hope to stop the invincible foe before the world plunged into darkness.
