The Crossing: Temple of the Mermaid Book Three

Joy enters Temple Eight with some notoriety and cred. Under the watchful eye of King Tetra (a "Metal" sounding name if there ever was one) she is conscripted into the Merman Military. More perks and a "Mid-Temple" lifestyle follow, but something ominous and inevitable looms at the edge of the undersea continental shelf. "The Crossing" takes us into the abyss and beyond.
