It all started with a curse.
When mermaid Sereia overshadows her brother and the kingdom’s rightful heir, Triton, the position of next ruler of the sea is in question. Determined to keep his throne, Triton banishes Sereia with a warning: if you ever return, you will become a monster.
Left for dead, Sereia washes up on the shores of Atlantis, where she is rescued by a kind merchant with a tragic past. He earns her trust, but Atlanteans fear magic and Sereia must conceal her true identity as her feelings for her savior deepen.
Her skill with a blade finds her a place within the Atlantean army, and Sereia soon wavers between the pull of revenge and the possibility of love on land, but when a friend’s fate is at risk, she must make the hardest decision of all: expose who she truly is and be burned at the stake as a witch, or return to the sea a monster.
