Wicked fantasies made Kiera famous, but in the Boundarylands the only thing they’ll make her an alpha’s possession.
In the beta world, the sexy alpha romances Kiera McIntyre pens under a fake name are strictly forbidden. Of course, that’s only made her readers want them more. When a nasty case of writer’s block threatens her livelihood, she decides to a covert research trip might refill her creative well.
Unfortunately for Kiera, there are no such things as secrets in the Boundarylands, and it’s only a matter of time before a massive alpha with piercing blue eyes sees right through her deception to the dangerous desires underneath…and decides to bring every one of them to life.
