Ruthless Alpha: Shadowed Heirs book one

Sloane Masters was my first everything.
My first friend, my first kiss, my first love.
My first heartbreak.
My only one, because Sloane didn't just break my heart, she tore it from my chest, threw it on the ground, and crushed it beneath her heel.
There's nothing in my chest now but a gaping hole where it used to be; the echo of a memory of what it was like to actually feel something.
Who's the real villain, the one without a heart or the one who rips out someone else's?
Food for f*cking thought, right there.
Sloane walked out of my life eight years ago, and in the wake of her departure, people say I turned cold. Callous. Ruthless. But now she's suddenly back, crashing into my life like a hurricane and upending everything I've built since she's been gone. Worst of all, she acts as though things can go back to the way they were before and we can just pick up where we left off.
She's wrong.
She'll learn soon enough that I'm not the lovesick boy she once left behind, and I'll never forgive her for the way she left.
Whoever said time heals all wounds was a liar.

Ruthless Alpha is book one in the Shadowed Heirs series, a collection of paranormal romance novels centered around six aligned packs of wolf shifters. These books contain mature content (steamy scenes!), frequent use of profanity, and darker themes. While each book in the series concludes with a HEA and no major cliffhangers, there are some loose ends concerning the overarching storyline that runs throughout the entire five-book series. Each individual book is a standalone, but the series is best read in order.
