Everyone loves mermaids. But take it from Slasher the unicorn-mermaids are NOT all they're cracked up to be. In fact, they're the mean girls of the underwater world. Pacey's not afraid of a few mermaids. She is just a little bit afraid of GIANT sea creatures and ANGRY Alpha unicorns, though. The last time she was in Unicorn land, Pacey lost the Alpha Unicorn's horn, and he wants it back! Can Pacey and Slasher find the missing horn... without getting on the bad side of any mermaids? Dive into adventure in the third Pacey Packer graphic novel!
