Lieutenant Ashwin Malhotra is a Makhai soldier - genetically engineered to be cold, ruthless. Unfeeling. His commanding officers consider him the perfect operative, and they're right. Now, he has a simple mission: to infiltrate Gideon's Riders, the infamous sect of holy warriors that protects the people of Sector One. He's never failed to execute an objective, but there's one thing he didn't anticipate: running into Dr. Kora Bellamy, the only woman to ever break through his icy exterior.  

Ana has trained most of her life to achieve one goal: to prove that anything men can do, she can do better. Now she's Sector One's first female Rider, and being the best is the only way to ensure she won't be its last. Distractions aren't allowed - especially not her painful attraction to the reserved but demanding leader whose stern, grumpy demeanor has already gotten into her head. Deacon has spent the last 20 years trying to atone for his past, but the blood he spilled as a mercenary and assassin will never wash away entirely.

Her wealth and influence have allowed her to build a better world, but they come with a price - the responsibility to secure political stability with a practical marriage. Maricela cherishes the idea of marrying for love, but there's not much romance in the endless line of suitors interested only in prestige and power. And her handsome, brooding new bodyguard isn't helping the situation.  

All Noelle Cunningham has ever wanted is a life beyond - beyond the walls of Eden, where only the righteous are allowed to remain, and beyond her stiflingly restrictive existence as a councilman's daughter. But only ruins lie outside the City, remnants of a society destroyed by solar storms decades earlier. The sectors surrounding Eden house the corrupt, the criminal-men like Jasper McCray, bootlegger and cage fighter.

Nina is an information broker with a mission - she and her team of mercenary librarians use their knowledge to save the hopeless in a crumbling America. Knox is the bitter, battle-weary captain of the Silver Devils. His squad of supersoldiers went AWOL to avoid slaughtering innocents, and now he's fighting to survive. They're on a deadly collision course, and the passion that flares between them only makes it more dangerous. They could burn down the world, destroying each other in the process....
