Love Circuits &
Siren Song &
Missouri Moonlight by Leigh Roberts, f/m contemporary 80-era romances starring computer programmers, musicians, and a chef, respectively. LC and SS are Harlequins that originally came out in 1984 & 1985, respectively. MM doesn't link to publication info, but is probably another one of the same unless the author was feeling really retro when she wrote it.
Frankie Warburton has always chosen logic over love, immersing herself in her work as a microprocessor systems designer. But her new job involves working with Dr. Julian “Jules” Jones, who besides having a knowledgeable and innovative approach to electronics, also dabbles in poetry and painting. Soon Jules and Frankie are studying chemistry--their own. Jules is sure where they're heading, but Frankie has trouble believing that an amorphous emotion like love really exists. Will logic circuits triumph over love? Revisit an age when computers were big and clunky, and romance was hot!

Race the Darkness by Carol Rose, a newly-written f/m contemporary political romance. Rose is a former Kensington Zebra/Precious Gems author.
In this romance laced with adrenalin, Kinkade Holbert races motorcycles like dying doesn't scare him. A successful attorney and the son of a senator, he's running from a past he can't forget and the conviction that he caused his younger brother's death.
While he's sexy as hell, Brooke McClendon has had enough trouble. Giving into her dying father's pleas, she helped him end his pain and went to jail for it. She's trying to get her life back together, but Kade's trying to get her attention and he scares her. Kade's not a risk junkie; he just doesn't seem to care whether he lives or dies.
Kade's struggles with believing he must take his dead brother's place and follow in his father's political path. Despite having a conflicted relationship with his parents, he feels he owes them. Crashing into his plans for atonement, the surprisingly less-conflicted Brooke makes him really hot at the same time she annoys Kade with her concern over his racing/sky-diving risk-taking.
Brooke has her own conflicted past, but she's at peace with her choices, even though these led to loss of her beloved career. Now, she's trying to put her life back together when Kade and his struggle crash into her awareness.
Kade doesn't think he's addicted to the adrenalin. It just helps him forget and it doesn't seem that big a deal if he were to end up dead. In many ways, he feels his brother should have been the one to survive. Brooke wants him to guard his life, but then she doesn't know who he really is.
When push comes to shove, Kade's future political life comes calling and he's thrown into crisis. He's not living his own life and he knows Brooke won't love him when she finds out the truth.
