Seafoam Friend For Madison #4

"Seafoam follows the adventures of Madison, a spunky 9-year-old girl who is granted passage to a beach full of mystical and nautical themed creatures after helping a beached narwhal. There she befriends a stand-offish boy she calls Blue, who has a few secrets of his own. Madison's trip to the island is turned upside down as a storm leaves her stranded. With no Blue in sight, Madison must survive the cold, dark, and eerie creatures of the night with only Alabaster and her backpack."
