Bound by Water — Monica La Porta

She can steal anything. Even his heart…

Atreides
I'm the last merman shifter alive.
I'm also a famous painter, richer than Croesus, and not in a hurry to find a suitable mate. Someday, I'll secure my heritage. For now, my life is perfect as it is.
And did I mention that in my spare time I help the police recover stolen art? Bringing to justice those thieves gives me a special pleasure, and I look forward to my next mission.
Ariel
I'm an art thief and exceedingly good at what I do but promised never to steal again. And if my father hadn't accumulated huge debts with the wrong crowd, I would've kept my word.
So here I am at night, outside the medieval castle I intend to rob when this absolute hunk of a man emerges from the sea. And what do you know, he walks up to me and kisses me.
It's not a regular kiss either, but the stuff of legend. I kid you not. I'm so shaken, I almost forget about the heist.
Too bad there's a werewolf biker gang after me, and I have no time for romance…
