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.
