Follow Percy, a boy who accidentally turns into a merman and threatens the existence of three young mermaids who guard Mako Island. (Percabeth/Jiper/Frazel/Temporary Perachel for Plot) *Basically PJO/HOO in Mako Mermaids Universe**DISCONTINUED*

What happens when the demigods meet the mermaids? Will there be friends or will there be enemies? (I stink at summaries, just come see for yourself. Basically the demigods will meet the mermaids, I mean this is a crossover that was going to happen anyway)

So basically the mermaids will meet the demigods.

After falling into a sacred pool of water during a magical ritual for the full moon, land-boy Percy inherits the powers of mermaids. Banished from the pod for letting a human tread on their consecrated island, mermaids Annabeth, Piper, and Hazel must take the power from him in order to rejoin their family. But the island's secrets go deeper than any of them realize.
