** spoiler alert ** 
 This is the first time that I read a story about mermaids. My love for them runs very deep, and I was very keen on knowing the story. I do love the names chosen for the mermaids in this story, such as Serafina, Isabella and Neela. The description could have been better, especially when the author was talking about the places (such as the palace) and the mermaid fins. She quickly described each merperson's hair color and tail color and that was that. 
 There are some things the author should have focused on to make the story appear more plausible. The fact that the items in the story did not float irked me greatly, as they were underwater and things aren't expected to just lie around like they do when above water. 
 Other than that, the author clearly forgot to the fact that merpeople cannot breathe above water, and there were instances in the book where the merpeople were out of water yet still could breathe normally. 
 Also, the clothes. I mean, merpeople aren't supposed to wear clothes!! Just look at the beautiful mermaids in My Little Mermaid! Their bodies were covered by beautiful shells, and that was something I missed in this book. How could clothes complement a mermaid's beautiful tail and fins? When I remember Neela's sari, I truly struggke to create that image. 
 The language used in the story disappointed me. As Serafina was royalty, she should not have resorted to words such as (party boy) and (totally). The mermaids were supposed to be high-class range creatures, just like elves, who should not be talking in weird teenage slang 
 Concerning the plot itself, it was interesting. The story on how Atlantis sank, and the mild description of its 6 rulers kept me interested. I also loved that there are six objects they needed to find and I am looking forward to the next book to learn what they are. The characters are strongly built and By far my favorite character is Astrid (love her hair).
