Published 1 May 2014
When Serafina, a mermaid of the Mediterranean Sea, awakens on the morning of her betrothal, her biggest worry should be about reuniting with handsome Prince Mahdi, her childhood crush. Instead she finds herself haunted by strange dreams foretelling the return of an ancient evil, and dealing with the deaths of her parents as assassins storm the betrothal ceremony, plunging the city into chaos. Led only by her shadowy dreams and pursued by the invading army, Serafina and her best friend Neela embark on a quest to avenge her parents' death and prevent a war between the mer nations. In the process they discover a plot that threatens their - and our - world's very existence.

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.
