Book 1

In this start to a new series starring Shelly the mermaid, a classroom conflict is no fun—even when school is 20,000 leagues under the sea.

It’s MerGirl Shelly Siren’s first day at a new school, and she is nervous from the tip of her head to the end of her sparkling mermaid tail. How will she ever fit in at the prestigious Trident Academy? Everyone there is so smart and so pretty and so rich. At least she and her best friend, Echo, are in the same class, but so is Pearl, a spoiled know-it-all who only wants to make trouble for Shelly; Rocky, a MerBoy who loves to tease everyone; and Kiki, a shy MerGirl who’s new to Trident City.
     At first Shelly and Echo have lots of fun: eating lunch together, trying to make grumpy Mr. Fangtooth smile, and joining after-school clubs. But when Shelly and Echo have an argument about their very first school assignment, Pearl gets involved and makes matters worse. Will Shelly and Echo fix their friendship?

Book 2

In this splashy new Mermaid Tale, a megapopular boy band is set to perform at an undersea celebration—but what if a mean girl keeps Shelly from joining in the fun?

Echo, Shelly Siren’s best friend, is doing tail flips because she’s going to see the hottest boy band around—The Rays! It’s her classmate Pearl’s birthday, and the Rays are going to perform at her exclusive party. Troublemaker Pearl has invited just about everyone—everyone, that is, except Shelly! Shelly urges Echo to go anyway, but Echo doesn’t want to leave her friend out of the exciting celebration…so Shelly hatches a plan to make sure Echo sees her favorite group. And when the Rays do come to town (amidst plenty of under-the-sea, boy band drama), Echo returns the favor so that Shelly is included in the festivities—in the most unexpected of ways!
