When Riley Cotswald, a writer at work on her second novel, finally leaves her husband, she gets way more than she bargained for.  Her characters' lives echo her own dilemmas, and she feels a kinship to them as they come alive on her desktop. Her best friend Jennifer does not understand this but loves Riley. 

Maybe too much.

After a particularly infuriating conversation with her husband Cameron, Riley impulsively gets involved with Edward, a socially-challenged man who had asked her out once, only to be rejected.  When Riley runs into him again, she takes out her rage and frustration in a way that delights and intoxicates Edward but was a one-time event for Riley.  Edward looks for ways to pursue the relationship but is frustrated at every turn.

He begins to stalk Riley and then resorts to the Dark Web to find ways to retaliate against her.

What follows is complicated, intense, and completely unforeseen.
