Shards of Etha (Clockmaster's Shroud #2): A Tale of the Dwemhar (Stormborn Saga Book 8)

Trusting a stranger has its advantages.

Valrin and his crew are captured. On an mysterious island, still locked in a dark cell underground, Valrin must work with a young female Dragonrider who has lost her dragon. A dragon Valrin believes is the only way they'll be able to break out the rest of his crew...

But this island is not just sacred ground to the Cult of Marog but yet a ruin of an old warlock, feared by the local villagers who believe their own horrid death is upon them.  As a lone volcano rumbles to life signaling the imminent destruction of the Island a deeper origin to a vile evil is hidden in the the dense jungles. The very jungles that Valrin must enter if he hopes to save his crew.

The workings of the Clockmaster tick closer to a coming darkness and no one will be able to stop what is brooding within the inferno beneath the island...

Not even a goddess.
