All of the creatures missing from the magical Underwater Kingdom have been found now, except for the octopuses. When Molly and Animal-Keeper mermaid Iona track them down they are surprised to find that there are no monsters on guard. Then a basking shark brings the message that the mermaid palace is under attack from the Dark Queen.
A great end to the series. Theis last one was action packed and dark as the sinister evil queen returned and battle ensued. A happy ending for the Mermaids and sea creatures though and peace was restored.a great series for any mermaid fan or sea creature lover. My 8 year old has loved reading them all.
