After dark by Jayne Castle (aka author Jayne Ann Krentz)
A race of aliens once lived on the future Earth colony called Harmony, leaving behind them the ruins of a vast, beautiful, and mysterious culture that is still protected by the psychic illusion traps and eerie ghosts that they created. Lydia Smith is an archaeologist who can resonate and dissolve the illusions, and those talents, combined with her lack of finances and questionable professional reputation, make her the obvious hire for Emmett London, who is trying to track down a lost antique and the nephew who stole it. Lydia's first consulting job quickly turns dangerous, however, as corpses, ghosts, and illusion traps start popping up--not to mention the rather unprofessional electricity between her and her first client. I like her futuristic romances, very fun to read.

After Glow
It's the second time in a month that Lydia Smith has found a dead body. The first time pararchaelogist and museum curator Lydia became tangled up in a murder investigation it brought her together with her current paramour, ghost hunter Emmett London. So naturally Lydia thinks of Emmett when she stumbles across the body of her former professor, Lawrence Maltby. While the police believe Maltby's death was caused by his drug addiction, Lydia doesn't buy it. So with Emmett's help, she pursues her own investigation even as she tries to figure out exactly what kind of a relationship she and Emmett have.

It is a good follow-up to the previous books and it's fun to be back in the futuristic world of Harmony.

Smoke in Mirrors by Jayne Ann Krentz a well known romance suspence author. I have read many of her books. This title features Leonora Hutton who is investigating her half-sister's, Meredith's supposidly accidental death. When she gets a delayed email from the grave she knows that Meredith was murdered. She meets Thomas Walker who is also looking into another related death of his sister-in-law Bethany. His brother Deke Walker doesn't believe his wife's supposed suicide. Were these women murdered and if so why and by whom? Lots of romance, more deaths and finally an ending that is not easy to foresee. I prefer her science fiction romances but this was fun.
