Beneath These Waves

Dell's sister Cal has always been the announcer of tiny disasters, so when she says that something is wrong with their father, Dell thinks nothing of it.
But it's not nothing.
Because their father is dead.
After the short but difficult task of moving the body to the freezer and suppressing stray emotions, Dell finds a note which leads to their father's dying request.
To find the six fragments of the Pluto Disk.
Dell, Cal, and their other sister Ser barely have any idea what it is or what it's for, but they're also stranded in the middle of the ocean on a submarine, lost, not even knowing where home is anymore.
And so, they set forth to fulfill what their father never could.
As the three of them plunge into a quest involving dangerous shipwrecks and intriguing mermaids, Dell is haunted by a torrent of questions.
Does the girl she left back on the island still love her?
Can she become the leader that her father was sculpting her into?
Can they even survive this?
The water is murky and so is her mind as she struggles to know if this quest is even worth it at all.

I'll be updating this story a few times per week.
