This novella is a fail on two counts, the main one being that whoever published it hates trees and the author apparently sees nothing wrong with this! In order to make a slim-to-nothing volume look worth the price, the publishers have made this disingenuous book have huge margins all around and widely-spaced lines such that the actual text doesn't even cover fifty percent of the page! I seriously doubt this is made even partially form recycled peper,, hence the publishers hate trees.
Naturally you don't want a page to be completely covered with text, but to allow this much white space is killing trees for vanity. Trees are one of the precious few entities on planet Earth which are actually combatting climate change. Not talking about it, but doing it! And these publishers want to slaughter trees for this book and not even respect that sacrifice by actually using the page? Screw them and screw author who allow this, and yes, screw people who buy these books.
And mermaids underwater having normal conversation in American English? Have you ever tried talking underwater? This author hasn't so let me save her the trouble: It. Doesn't. Work. Maybe they were communicating telepathically, but the author never says that. But it gets worse! This is an African slave who went overboard. She spoke no English, American or otherwise. I don't expect it to be written in some West African dialect, but neither did I expect it to be modern American English! The slaves didn't go overboard yesterday so even if they spoke English, it wouldn't be modern! I expected something to convey how alien these mermaids are even though they're purportedly descended from us. This book is ill-conceived and environmentally braindead. Warts all over. I'm done with this author. I tell you the more acclaim an author has, the more awards and honors, the less worth reading they are. Truly.
