Meet Esmerelda Sleuth. Sleuth is her name and investigating is her game. (Paranormal Investigating, that is.) Esmerelda makes a good living as an investigator in a rather progressive firm. She lives a stable and sensible life until she meets Lance; an old money "hottie" who works for a real estate firm next to her building. After accepting an invitation for a weekend getaway party, she quickly discovers that Lance has a secret. He is wealthy. That part is true. And, yes, he's procured a job as a realtor in the building next door. His secret is that he belongs to an underground society of humans who didn't abandon their connection to magic centuries ago when religion declared it evil and he has traveled through time specifically to find her and bring her back to his time to marry him. If that isn't enough of a far fetched tale to absorb, he informs her that she was born in his time to a family belonging to that same secret society and was promised in marriage to him as an infant. When enemies who didn't want to see the union of families take place made attempts on her life, her parents sent her into the future and erased her memories of them as a precaution. Possessing virtually no belief in magic, ghosts, psychics, time travel, etc., it takes some doing on Lance's part to convince her to believe his story and go back with him. When she does, the lies, deceit and attempts on her life start all over again. Will she escape emotionally and physically unscathed? "The Other Side Of the Mirror" is a steamy-paranormal-romance- mystery-thriller and book one of the Esmerelda Sleuth series.

With her enemies in pre-civil war Virginia still seeking her death, Esmerelda is forced to return to the future only days after wedding Lance. Because it was necessary to fake her death in order to stop her enemies from following her to the future, her new husband, Lance, was forced to stay behind. He’d placed a magic box for them to communicate until he found a way to safely be with her beneath the floorboards of the house. Now, she must find it. A task that is easier said than done! “The Magic Box” is book two of the exciting paranormal-romance-mystery-thriller Esmerelda Sleuth Series

Detective Casie Blackwood thought she'd left her supernatural past behind when she joined the police force ten years ago, fleeing the shame of public mate rejection and family abandonment. Now, ritualistic murders are forcing her back into a world she desperately wanted to forget. Three human victims have been discovered with surgical precision wounds and ancient symbols carved into their palms—markings that point to forbidden blood magic from before the supernatural communities established peaceful coexistence. When Casie finds a note written in the old pack language reading "The Hunt Begins," she realizes someone is deliberately targeting humans to harvest their primal fear, threatening to expose the entire supernatural world. Partnered with Detective Rick O'Connor, who remains unaware of her true nature, Casie must navigate the investigation while concealing her enhanced senses and knowledge of the supernatural. The wounds aren't from blades—they're fang marks. The positioning isn't random—it's ritualistic. And the killer's scent carries a terror that suggests they're being hunted by something even more dangerous. Forced to break ten years of silence, Casie contacts her estranged brother Elias, learning the symbols are ancient binding marks used to channel supernatural energy across factional boundaries. The killer needs seven sacrifices total to complete a ritual that will shatter the barriers between the human and supernatural worlds. With three victims already claimed and only four days until the next lunar cycle, time is running out. As federal agents circle and media attention intensifies, Casie must choose between maintaining her carefully constructed human life and embracing the supernatural heritage she rejected. The investigation isn't just about stopping a killer—it's about preventing an all-out war that could destroy both worlds she's sworn to protect.
