Dane Thorburn and The City of Lost Souls

Dane Thorburn returns in another fast-paced fantasy adventure.
Rewarded for thwarting evil Firelord Raegan''s plan to kill the King and seize power for himself, Dane has joined the elite ranks of Brindabeare''s Royal Knights.
But Raegan''s desire to rule all Valentaland is far from over.
Princess Vanessa is missing - snatched by Raegan''s Black Knights and on her way to the City of Lost Souls, an ancient prison somewhere in the Gargaun Ranges. Dormant and unused for centuries, the City of Lost Souls is a place from which escape is impossible and death inevitable.
As the frantic search for Vanessa begins, Dane finds himself on trial for aiding her kidnapping.
Can Dane prove his innocence and do anything to save Vanessa before she is lost forever?
