The Tail of Emily WindsnapEdit
Shona first starts on Emily when she is practicing Beauty and Deportment. Her first word to Emily is "Oh," which is said because of her legs. Emily's first word to her is a pleading cry. "I'm a mermaid, too!". Shona, who was swimming away from Emily, came back when Emily showed Shona her tail. They chat and are on the road to becoming friends.
Shona takes Emily to mermaid school later in the book. Emily describes it as a giant underwater rabbit warren. She is astounded by how many mermaids there are. Shona introduces her as a cousin. Their first class is Shipwrecks, which to Emily, beats Pre- Algebra. Shona and Emily learn about a ship that was called The Voyager , how it sunk, and who did it. A group of mermaids, called the Siren Sisters, had sunk it. The teacher of the class, Mrs. Tailspin, told the class that the one problem in the sinking was what one or two of the Siren Sisters did. They fell in love with a human, which is illegal. Shona explains who Neptune is to Emily.
Shona inspired with curiosity, peer pressures Emily to go with her to The Voyager. Shona used her splishometer every few yards. They soon found it. The ship was surrounded by a hazy golden light. Emily feels uncomfortable due to the shipwreck made of gold. When Emily frantically demands Shona to check what the mast is made of, Shona says that it looks like marble. Shona found a broken porthole to gain entrance with. Inside, the floor is white. Shona declares that it's pearl. Emily again panics, when Shona says that the ceiling is amber. Shona does not know that The Voyager is the ship from Emily's mom's dream. Shona is forced to leave by the scared Emily Windsnap. The girls find a door with a pitchfork on it.
Back at school, Shona helps Emily find out how she faintly knew Emily's last name, Windsnap. The mermaid had heard it at school. Shona takes Emily to the school library and they attempt to find out in a scroll called Sirens. Mrs. Tailspin demands to know why is Shonal here. Emily lies that Shona is helping her with homework on illegal marriages. Mrs. Tailspin tells the two about the one illegal marriage in Shiprock. The merman and human met when the woman was saved by the merman when her boat capsized on rocks. They soon became enamored. Whe, Shona questions Mrs. Tailspin on what the merman's last name was, Mrs. Tailspin said " Whirlstand? Whichmap? Wisplatch? No, I can't remember." Emily asks " Was it Windsnap?" Mrs. Tailspin said " Windsnap! That might have been it." She also said that Windsnap was in prison. Neptune had gotten him when the female brought the baby to rainbow rocks to meet him.
Shona takes Emily back to The Voyager despite Emily saying that Jake Windsnap was not her father. Shona leads Emily to the door with the pitchfork on it. Shona says that she almost forgot the trident, Neptune's Symbol, on it. Emily takes Mr. Beeston's keys and opens the door with them. In the room, Emily uses Mr. Beeston's keys again to open a chest which contains files, one with Windsnap on it. To Shona and Emily, it holds papers of gibberish. They did make something out of it though, they find out that Jake Windsnap is Emily's father. They plan to find him at the prison on Sunday.
Shona finds Emily, her mom, Mr. Beeston, and Millie on the King of the Sea on Monday. Shona arranges for her to pull the boat, due to the boat running out of fuel. Earlier, Emily had thought Shona's tail was a shark fin. Later, Emily joins Shona in the water, where Shona asks, "Are you ready?" They head out to meet Emily's dad in the Great Barrier Reef. When trying to get past the reef, Shona finds a weak spot in the reef. She show Emily how to scrabble in it and make it larger. Shona is unable to fit through the tiny hole, but Emily can. The two girls are unable to make the hole larger. Shona is forced to stay behind when Emily goes in.
During the court meeting with Neptune, Shona is mentioned as the " other merchild?" Neptune barks that Shona can join Emily and her family in Allpoints Island or get memory wiped. Shona is inside a limousine/submarine waiting for Emily to go to Allpoints Island. Emily explains to Shona what happened on the way to the Island. Shona in farewell, says " See you soon. In the end, Emily describes Shona as a best friend. She also gives thanks to Shona to reporters.
In the next book, Shona moves in with Emily on Allpoints Island where they get in serious trouble.
