The Shark

Souls shrouded in darkness…
Focused on her studies and duties at the aquarium, Jewels prefers her solitary life. Burned many times and short on trust, she has more in common with her aquatic friends than the people around her. But she never imagined coming face to face with a shark named Clarence…a shark who talks!
As their friendship grows, Jewels must overcome her deep set mistrust. There are dangers, both in the Australian ocean and on dry land. Can Jewels depend on the great white or will his animal nature betray her?
