Catalyst

Natalie Tyler wants one thing from her trip to Chicago: to survive a family wedding without falling apart. She has an ex-fiancé to avoid, old wounds to keep buried, and a flight home waiting on the other side. What she does not have is a plan for Jaxon Pace — billionaire, hotelier, and the man who quietly controls the city's criminal underworld. A single unguarded moment pulls her into his orbit, and once Jaxon decides he wants something, the world tends to rearrange itself around that desire. Nicole Fanning builds her central tension not around action alone but around the collision of two people who have every reason to stay apart — and can't seem to manage it.

Fanning writes with momentum. Her pacing keeps the pages turning without sacrificing the slow-burn tension that makes the central relationship feel genuinely earned rather than rushed. The Chicago setting carries real atmosphere, and the power dynamics between her leads are drawn with enough complexity to keep readers off-balance in the best way. As the opening book in the Heart of the Inferno series, Catalyst does exactly what a first installment should — it plants hooks early and makes the next book feel less like a choice than a foregone conclusion.
