Molly returns to the Undersea Kingdom to help Animal-Keeper mermaid Leila find the missing whales. When they investigate they find the whales trapped inside a lobster pot but before they can set the whales free Molly and Leila are attacked by the Dark Queen's menacing mud monsters.
Another fantastic read in this series. Things are getting more frightening for the Mermaids as The Daek Queen Carlotta sends more and more monsters to attack as the Mermaids seek to free the captured animals. More worryingly, the animals appear to be losing their special abilities. What has the dark queen got planned? She seems to be harnessing the collective powers and tension is building for her imminent return.
