Tell Tail

There has always been something about Bay, a self-proclaimed flop whose only success, however serendipitously it came, was splashing out of depression.
When every living thing under the water is faced with endangerment, the very unlikely Bay faces her devout kingdom with an answer to their prayers: her secret and a deliverance. With this, tides changed for the mergirl. Forgotten was all that she lacked in the past: her failings, chronic self-doubt, and always being a far swim behind. To her delight, no longer was she discounted.
On the wave of her redemption, which leads to her being celebrated, she discovers something very telling. It hints that in Lucaya, a kingdom populated with pious mermans, she is swimming in waters polluted with a half-truth.
