One clue… what does it mean?

Ken, the leader of the Blue Men of the Minch, has kidnapped Evan. Before they left, Evan was able to leave a package for Meara―her grandfather's necklace wrapped in a cloth napkin with one word written in blood. Azuria. Unfortunately, Meara doesn't understand it and neither does her dad or Kieran.

When Dad and Aunt Brigid attempt to rescue Evan, Meara and Kieran begin to train the clan on how to fight and defend their home. A war is brewing, and Meara is determined their people must prepare for the battle. The training sessions are long and arduous, but the Selkies work hard to learn.

Meanwhile, Evan wakes and finds himself in Belle Tresor, the home of sirens. He's bound to his blue form, unable to transform to human, and Ken has plans to use Evan's powers to destroy the Selkies. Thankfully, he's not alone. He befriends a siren named Deanna and several Blue Men. Can he trust them to help him escape or do they have ulterior motives?

As both sides prepare for an ultimate confrontation, the stakes are high and friendships are tested. Some will rise to be victorious. Some will be destroyed. But love and loyalty will be always remembered in this exciting conclusion to the Never Forgotten series.
