Tempest Maguire is happy with her decision to embrace her
mermaid nature and live among her motherβs clan within the
oceanβs depths. Even though training to one day ascend the

refuge in the arms of Kona, the selkie who first opened her
up to her mermaid side.
But when word comes that one of her
brothers has been gravely injured on land, Tempest

her old flame, Mark. And in her absence, a deadly battle
begins raging at the hands of Tempestβs old nemesis, the sea
witch Tiamat. As the dangerous war erupts, Tempestβs two
lovesβKona and Mark, sea and landβwill collide for the first
time, both to protect her and to force her to choose.
