Stalked by the Alphas

My life was supposed to follow a perfect path—a nice job, mated by twenty-five, and children after that—but fate has other plans.
Now, a week from turning twenty-five, I have a successful bookshop that I love, but the rest has remained elusive. Always within my reach but never managing to hang onto an alpha for long enough to mate. Then there is the pact in the back of my mind. An alcohol-fuelled promise on my twentieth birthday, jokingly giving my alpha childhood friends a chance if we're all single in five years.
I'm as single as they get, but who knows about them? We drifted apart when I moved up North to start my new life.
That's when things turn a lot darker. I discover I have a stalker. Someone who knows me inside out, and this twisted obsession has turned dangerous.
My life isn't mine anymore. It belongs to him. To them.
This is a non-shifting, dark, psychological thriller, reverse harem omegaverse standalone with a romance sub-plot. Please note this is set in England in a completely fictional world.
