Black Sea Bright Song - Poseidon's Blood, #1

Evan is in a real life version of kiss/marry/kill and things are getting tense. With newly discovered sea witch powers and Sirens on the loose, how's a girl supposed to navigate first love?Mermaid Princess Evannia is in lust. She's caught up in a secret affair with Rafe, her raven-eyed guard, despite knowing she won't be allowed to choose him on her Thrice Day. Ugh, Thrice Day. She'll turn 20, the age that Mer are finally considered adults.
But she'll also be officially named heir of the Triton kingdom AND have a gigantic celebration where she'll have to choose her future husband. That is, if she even makes it to her Thrice Day without her mother forcing her into an alliance with Prince Calix, the future king of neighboring kingdom of Protea. But none of that matters when the Sirens attack. Triton's oldest enemy has returned, their silver eyes flashing and seductive songs pulling at Evan's soul.
She doesn't know what they want, only that their tridents are aimed at her. Forced to flee the ocean to avoid capture, Princess Evannia finds herself in the last place she ever imagined. The sea isn't safe, but land is full of the unknown, and worse, humans. Outside the protected life she's lived, surrounded by human inventions and wonder, she finds her spirit--wild, unafraid, fierce. The woman who returns to the sea to save her kingdom is not the same naïve princess who fled: she is the blood of Poseidon and she will not run.
