Book 10
Join the entire gang of mer-friends—and celebrate twenty years of Emily Windsnap—in this epic and masterfully crafted adventure by New York Times best-selling author Liz Kessler.

Adventure always seems to find Emily Windsnap! So when she discovers a bangle with a unique crystal under Rainbow Rocks, she and her friends are soon unraveling a whole new mystery. After learning that the crystal originally came from a familiar place—Halflight Castle!—Shona and Emily reunite there with Aaron . . . and none other than Neptune, king of the oceans. The bangle leads the mermaids to a cave full of crystals, and, with Mandy’s help, they discover the truth about the jewel’s origin—and what’s at stake if they don’t make things right. Unfortunately, the only solution involves getting the sea and sky’s most powerful (and notoriously selfish) rulers to put their own interests aside for the greater good. Will the quartet find a way to convince the imperious Neptune and the Viking god Thor to come together to prevent disaster?
Book 9

When Emily makes a wish on a magic stone, she gets a glimpse of what the future holds — and it’s a disaster! She tries to make things right, but each trip through time takes Emily to a future where things turn out badly for either the humans of Brightport or the merpeople of Shiprock. Plastic pollutes the ocean, garbage overflows the landfills, and the two towns are no longer getting along. Emily realizes she can’t save her hometown and the ocean alone, but with help from her best friends, Shona and Mandy, she’ll have to find a way to get humans and merpeople to work together. Will Emily be able to create a better future for everyone, including herself? This new adventure gives readers a glimpse at what Emily and her friends could be like as grown-ups, with a fresh story that explores how uniting communities can make a future that’s bright for everyone.

Emily Windsnap ends up surrounded by pirates — and on a life-changing adventure — in the eighth installment of the New York Times best-selling series.

Traveling home by cruise ship should be a relaxing break after Emily’s latest adventure, but things take a turn when the ship is overtaken by a pirate king and his crew. After the pirates collect everyone’s riches, the pirate king’s eldest son steals something even more valuable: Aaron. So Emily dives into action and joins the younger son’s crew in hopes of saving her boyfriend. But Emily is surprised to find herself not only enjoying the pirate life, but actually bonding with the crew — especially Sam, the pirate king’s son. Between helping Sam unravel riddles to beat his brother to the legendary Trident’s Treasure and making sure that her friends are safe, Emily realizes that she needs to be true to herself. Will she cast aside her mermaid life to join her new friends, or will she find a way to follow her own path?

While on vacation, Emily Windsnap finds herself swept up in an ancient prophecy as the New York Times best-selling series continues.

Emily is headed to a tropical island for a relaxing vacation with friends and family. And this time, Emily promises her best friend, Shona, there will be absolutely no adventure — just plenty of fun. But somehow excitement always seems to find Emily, and before she knows it, she ends up on the other side of a powerful waterfall on a forgotten island no one else can get to. Well, no one that isn’t a half-mer like Emily and her boyfriend, Aaron. The people who live on the island believe in a prophecy that foretells how they can be saved from an imminent, devastating earthquake — and this prophecy seems to revolve around Emily and Aaron, as well as a mysterious, mythic giant.

Only Emily, with her ability to transform from mermaid to human, can enter Atlantis to try to bring the ship’s passengers back before the portal is closed forever. Will she be able to resist the allure of Atlantis and return home before it’s too late?

“A successful mix of fantasy, mystery, adventure, and a touch of romance.” — Kirkus Reviews 

The New York Times best-selling series continues with half-mermaids Emily and Aaron embarking on an icy and perilous journey to the Land of the Midnight Sun.

Book 4
The fourth audiobook in the best-selling series about half-mermaid, half-girl Emily Windsnap!

Emily Windsnap’s life on Allpoints Island seems perfect—her family is all together again, and she has both her best friend, Shona, and her new friend Aaron with her there. Somehow, though, it still feels like something—or somewhere—is missing. So when Neptune gives the Windsnaps a mission that sends them all back to Brightport, their hometown, what could be better?

But as construction in Brightport threatens to destroy the nearby mer-town of Shiprock, Neptune’s desire to have humans and mermaids come together seems impossible. Between trying to help humans and merfolk get along, sorting out her growing feelings toward Aaron, finding some missing sirens with Shona, and dealing with her old enemies Mandy and Mr. Beeston, Emily certainly has her fins full!
Book 4
The New York Times best-selling series

Follow the siren call to Emily’s magical adventure! Can the spunky half-mer girl pass Neptune’s test—and help humans and merpeople get along?

Emily Windsnap is finally enjoying a swimmingly peaceful life on Allpoints Island, hanging out with her mermaid BFF, Shona, and her new friend Aaron (half-merperson like herself ). But their idyll is cut short when Emily learns that the Windsnaps and friends must return to their old home in Brightport, where construction projects are threatening a secret mermaid community under the sea. Neptune’s mandate? No less than an interspecies intervention to bring merpeople and humans together, a task the imperious god feels the mixed Windsnap family is well suited for. There are just a few snags for Emily, however, like dealing with old nemeses Mandy and Mr. Beeston, figuring out her feelings toward Aaron, and untangling a high-suspense mystery related to a group of legendary lost sirens. Everyone’s favorite half-mermaid is back with a splash in a sparkling adventure her fans will be eager to get their fins on.
Book 3
Everybody has a secret. Mine’s a little different, though. I didn’t even know about it until the first day of swim class in seventh grade. You see, I’d never been allowed to go in the water before. As it turns out, swimming comes naturally to me. Very naturally. In fact, so naturally that you might even say . . . well, it’s true.
 
Here’s my secret: I figured out that I’m a mermaid.

“An easy sell to girls looking for a friendship story with more than a touch of make-believe.” — Kirkus Reviews

When Emily Windsnap discovers an old diamond ring during a class hunt for trinkets, how is she supposed to know that the ring is half the key to unlocking an ancient curse by Neptune himself? Now, with the ring stuck firmly on her hand, Emily finds herself under a new curse: in just a few days, she’ll cease to be half-human and half-mermaid and must say good-bye to one parent forever. Can she possibly find the other missing ring that will break all the curses? Is there anyone who can help her — before it’s too late?
Book 2
All I wanted was to impress my best friend, Shona, and the other mermaids who live in the sea around Allpoints Island. But what did I do instead? I woke up the kraken, a terrifying octopus-like monster the size of an apartment building. Now he’s coming after everything and everyone I love. And who can stop him? You guessed it. Me. Well, me and Shona, and another person too–someone I’d hoped never, ever to see again.
