The Case of the Pisces Moon Murk is the seventh book in the Wolflock Cases teen fantasy mystery series.
Creast Bay is known for its pristine waters, beautiful gemstones, and the mermaids that gather at the Pisces Moon festival. So, why is Wolflock instead met with a murky pond? What, or who, has contaminated the once beautiful bay? As they hunt for the answers, Wolflock and Mothy discover that not all is as it seems. Shady deals, unchecked disease, and a peculiar tour guide lead them closer to a dark truth. Even if Wolflock can solve the case before the festival, he may not be in time to cure the bay and save the mermaids from disaster.
