Dark lords, aliens, and vampires await as she struggles to save her friend from the vampires by aligning with aliens who she later learned were cannibals! Through it all, she's finally reunited with Lance... but what about Killian? The thrills, suspense, and romance continue in "Beyond the Portal", book 3 of the Esmerelda Sleuth, Paranormal Investigator 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

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.

Forced to return to the past and then venture back into the realms of the dark lord to save her friend, Esmerelda faces loss, love, and a new awakening in this final installment of the Esmerelda Sleuth Series. Filled with excitement, love, loss, time travel, family dynamics, dimension hopping, and a few vampires, this is the completion of a story that you won't want to miss.

In a war-torn world where supernatural beings known as "subnaturals" or "subs" have emerged from hiding, triggering a global conflict that has claimed hundreds of thousands of lives, eighteen-year-old Lena Hargrove has spent the past six years as a ward of the state following her parents' deaths. Renowned as war heroes who sacrificed themselves to rescue their daughter from kidnappers, Lena's parents were largely absent throughout her childhood, leaving her with complicated feelings about their legacy and her own identity. As Lena struggles to understand her newfound identity and the abilities that begin to manifest, she uncovers a web of secrets about her parents' true role in the war. They weren't just fighting for humanity; they were part of a hidden movement working toward peace between humans and subnaturals. More importantly, Lena learns she was kidnapped not by chance. Hunted by extremists from both sides who either want to use her power or eliminate her entirely, Lena must navigate a dangerous landscape of political intrigue and ancient supernatural factions. Along the way, she assembles an unlikely group of allies—humans sympathetic to the sub cause, subs living in hiding among humans, and others like her caught between worlds. As her powers grow and her understanding of both sides deepens, Lena realizes that ending the war might require more than diplomacy or combat—it might demand a fundamental reimagining of what it means to be human or supernatural in a world where the boundaries between the two are increasingly blurred. But to fulfill her destiny, Lena must first confront the truth about her kidnapping, her parents' sacrifice, —a truth that will test her loyalty to both sides of her heritage and force her to decide what kind of world she wants to fight for.
