Two Flames, One Inferno

Calder built Aegis Grid to cool a burning world. Now someone turns his network against him. To stop catastrophe he needs two women who read danger in different languages: Rae Navarro, a scarlet-dress white-hat who can out-code a ghost, and Tamsin Leigh, a former fire investigator turned crisis medic who can feel a blaze before it breathes.

As threats leap from server rooms to rooftops, a black-tie gala tilts toward disaster, a “helpless” hotel grows teeth, and a whisper called Helios points to a cofounder who died—or didn’t. To keep millions safe, the three of them will break into a forgotten data spine, stage a false breach, and hunt the money behind the flames…all while the city clocks down to dawn.

He owns the grid. She owns the code. She owns the fire. Together they’re the only firewall that matters—and the kind of trouble none of them can resist.

Billionaire why-choose romantic thriller with high heat, forced-proximity safehouse, corporate intrigue, and rooftop-at-sunrise stakes. Fully consensual triad. Disaster peril and non-graphic violence. A blazing, guaranteed HEA.
