A Merformer's Blessing: Book 1

Moana, Pearl, and Keo have always been in love with the big blue and its inhabitants. Their favorite are the Merformers. Humanoid torse and a sea creature bottom .... kind of like a mermaid and merman but not just a fish tail. Little do they know they were blessed by Merformers before they were even a thought! Or before their mother was pregnant with them anyway. Though they've never noticed it.
But after going to the MSR during a field trip, their life has been turned into a completely new world. The MSR, scientists, and everyone worldwide are shocked by this discovery and want to study them. MSR makes the decision to take the kids under their wing and convince the upper people to allow them to do it. Unfortunately, they are only given 2 years to give feedback intel of the blessings.
How will the kids manage to do their daily lives? How did they discover the blessing? How will MSR help? Will they manage to do it in time? Or will they run out of time? And who ... gave the blessing?
