A Hard Habit to Break (The Calvary Brothers, 2) by Siera London

At age eighteen, Rachel Johnson left Service, West Virginia with a college acceptance letter, a broken heart, and a blueprint for a new life. Now the star architect is back, for two weeks, and not a second more, for her dad’s wedding—and zero intention of rekindling old flames. But when she’s roped into the town’s redevelopment committee to bring much needed resources for the community, she finds herself face-to-face with the committee chair ... her ex, Noah Calvary.

Firefighter Noah volunteered for this assignment to further his career, not to work with Rachel. A born competitor, Noah isn't thrilled to share the spotlight with the woman who once left him in the dust, but to help the town, he figures he can play nice. And his success could clinch the promotion he’s been angling for.

Rachel’s got vision and a partnership at her firm on the line. Noah’s got a promotion to protect. And every decision is a battle of wills. Their history is messy, but their chemistry is explosive. Between small-town politics, big-time rivalries, and sizzling glances, Noah and Rachel must decide if they’re laying the foundation for professional disaster or finally building something real.
