Lonnie the Lobster Knight and a Seahorse from the isle of wight

Lonnie the lobster has always dreamt of becoming a knight and somewhat of a Don Quixote. He wants to travel and help and protect the sea and its life. Regina the little herring from Santa Marina is a prima ballerina. She writes to him that she will love only the one who will dare to be adventurous and she will not wait because the son of the Sea Bream is very polite, brings her silky seaweed ribbons every day and is sure to be daring to impress her. This is how Lonnie begins his adventures at sea. What will happen when on his way he meets Dwight the Seahorse and a monster? How will Lonnie help the sea and its life? Will he make it to knight school? What will Regina do when she reads "The News of the Deep?"
