Ara's Song - The Selkie Chronicles, #1

Book 1 of The Selkie Chronicles When Selkie Princess Ara loses her sealskin struggling with a fisherman, her fate appears hopeless. Trapped on land, unable to transform back into a seal, she'll be bound by this human beast for life.     Young Seamus turns out kinder than expected, though he doesn't return her sealskin and set her free. Not that this would solve the problems she and her Selkie pod are facing.
Their North Atlantic Ocean is dying. What few fish they find are too toxic for humans or seals to eat.     From her new vantage point among the land folk, Ara can see what's causing this desolation. But can she and her new friends do anything to help?
