Littoral Magic — Leslie Ann Moore

For Ayana Outerbridge, a biracial fourteen year old girl, summer vacations on the evergreen Pacific Northwest coastline had once been a time of play and relaxation. But now her father is dead, and all that was bright is now dark. Until one day she finds a strange and startlingly beautiful seashell... Just off shore, the river otter Sleek has broken the Law. He has entered the forbidden Garden to retrieve a mind-elevating gift for his true love Gloss, headstrong daughter of the sea otter king. His trespass threatens to push both otter tribes closer to all-out war. But will Gloss follow her heart or the laws of her people? The fates of Ayana, Sleek, and Gloss will soon converge -- and when they do the sea will shine with an otherworldly light.
