Description

Dive into the international bestselling ecological fantasy where a young girl unravels her mysterious heritage—she is a descendant of the Sea People, beings who command the ocean's depths and transform into mermaids.

A powerful tingling sensation spread through her whole body, flooding from her head to her toes like a raging tsunami. She wished more than anything that the world beneath the waves would awaken to new life. Could she be the one to make this dream reality?

Alea has a dream: she wants to bring all the mer-children scattered around the world back to the ocean. But how is she supposed to bring the extinct underwater world back to life if no one besides her and Lennox else can survive in the contaminated water? The Alpha Cru sets course for Iceland, where they have heard that there are still surviving merpeople living in the hot springs. There Alea wants to finally find her father – and the answers to all her pressing questions. Can Alea's father help her make her dream come true?

Answers await in the third volume of the great Mer-girl Saga from bestselling author Tanya Stewner.

What an adorable and sweetly emotional children's story. I love this. The secret of the Oceans is no longer a secret to me. ( couldn't resist a pun).

This was a strong third entry in the Alea Aquarius series, it had that element that I enjoyed from the previous two books. Tanya Stewnerhas a strong writing style and I hope to read more from this series and author.The characters had that feel that I was looking for and enjoyed the historical setting going on. The plot was everything that I was looking for and worked with the sea people element to this.
