Once a lost and confused princess, Serafina is now a confident leader of the Black Fin Resistance (BFR). While she works on sabotaging her enemy and enlisting allies for battle, her friends face challenges of their own. Ling is in the hold of Rafe Mfeme's giant trawler, on her way to a prison camp. Becca meets up with Astrid and learns why the Ondalinian mermaid is always so angry: she is hiding a shameful secret. Ava can't return home, because death riders await her arrival. And it is getting more and more difficult for Mahdi, Serafina's betrothed, to keep up the ruse that he is in love with Lucia Volerno. If Lucia's parents become suspicious, his life--and all of Sera's hopes--will be extinguished. Political intrigue, dangerous liaisons, and spine-tingling suspense swirl like a maelstrom in this penultimate book in the WaterFire saga.
Praise for Deep Blue
"A richly imagined novel. Themes of conquering fear and believing in oneself are woven throughout, along with an acknowledgment of humans' environmental impact on the sea and its inhabitants. Despite the high stakes and a few frightening moments, the story is never over serious; it's just right for readers who have grown up with, but aged out of, The Little Mermaid and the Disney Fairies franchise."
- Publishers Weekly
"A fantastic addition to the genre of mermaids, this book will also appeal to readers of action and those who appreciate usurped leaders taking back their kingdom. It starts with a common enough concept: a royal girl who is worried about her betrothal and about love. Donnelly then adds layers of complexity to the tale and weaves her story into that of Atlantis. Friendship, trust, and responsibility are major themes as Sera struggles to grasp that she is really her kingdom's only hope. Quick-witted, loveable characters and a well-planned fantasy world make this an all-encompassing book. Readers will eagerly await future volumes and the answers they will provide."
"Best-selling Donnelly (Revolution, 2010) builds an alluring mermaid civilization and history, filled with painterly descriptions of Sera's underwater palace and its unearthly architecture, her sumptuous wardrobe, and the menagerie of half-human, half-marine animal denizens. There's also plenty of romantic tension with handsome mermen, strife between merls (that's girl mermaids) from rival regions, and some powerful female friendships amid the fast-paced plot, filled with wondrous magic."
