turned and finally noticed I was there.
Jade, Serena rang to me in her mer voice, smiling broadly.
Most people would probably think the ringing sound of Serenaâs mer voice was actually buzzing from the overhead fluorescent lights because thatâs what it sounded like to non-mers. I thought mer rings were one of the most annoying sounds on the planet, but that was how all mers communicated.
I still didnât know what on earth was going on, but if Serena was going to be human again, I had to break her mer-speaking habit as quickly as possible.
You need to use your human voice, I rang back and hugged her. Remember?
Serena knew the basics of English from what sheâd learned from me and Mom last time she was human.
âJ-shadeâ¦â Serena tried again. Her eyes widened in surprise at the sound of her voice. She turned to Gran and pointed to the map. âGrr-ansh. Water? Mother, Father?â
âYes, honey,â Gran said in a hushed voice. She pointed at the map as if giving a stranger a tour of local landmarks. âThis is the bridge we crossed at the canal between the ocean and the lake. And hereâs the school where we are now, and there is where I live, remember?â She pointed to Dundee on the map, halfway up the lake.
âThish what?â Serena asked as she pointed to the northernmost part of the lake where it connected to the Atlantic Ocean again.
âThatâs Follyâs Passage,â Gran explained. âIt connects the lake to the ocean up north, but itâs only open during the highest tides of the year. Thereâs actually a famous shipwreck around there from the Second World War called Fortuneâs Folly . The captain missed the tide and ended up capsizing. Divers have been trying to find the ship ever since.â
âYou mean the canal by the bridge isnât the only way in and out of the lake?â I whispered to Gran, trying to talk quickly so Serena wouldnât catch on.
âWell, Follyâs Passage hasnât been used since I was a girl,â Gran mumbled back as Serena kept studying the map. âThe cliffs have eroded so much from all the forestry people clear-cutting the trees that the passage has filled in, making it pretty shallow. Youâd be crazy to take a boat through there now.â
I considered this for a second. Most of the Freshie mers hung out by the boat lock at the south end of Talisman Lake where salt water spilled in from the canal. Other than Finalin and Medora, whoâd been in the lake the longest, none of the Freshies had made it further north than Dundee because the lake water was too fresh. There was no way any of them could ever get past the freshwater barrier in the middle of the lake and reach the northern passage to escape. The Mermish Council had the Freshies trapped and imprisoned in the lake, just like they wanted.
âOkay, then.â Gran pulled out a sheet of paper from the stack Ms. Wilma had given her and handed it to me as we headed out of the office. At the top it read: New admission: Serena Finora . âGive this to your homeroom teacher and let her know Serena is a new student. Sheâll have all her classes with you. Hereâs her class schedule, some school policy information, and this oneâ¦â
âWait, wait. Back up the truck for a sec,â I said, balancing the papers Gran had handed me. âNew student? Whatâs going on?â
âCome.â Gran guided Serena and me out of the office to where Cori, Trey, and Luke were waiting. Gran shuttled us to the bench just outside the school office door.
âThe thing is,â Gran whispered, looking around to make sure no one was eavesdropping, âSerenaâs father and your parents and I have come to a bit of an agreement.â
âYou met Finalin?â I asked.
âYes, such a charming fellow.â Gran smoothed her slacks and looked from Serena to me. âSerena had left your necklace on
