The Merger Clause. Marlowe & Cole, #1

She just found out her father's company got swallowed whole. He just became her new boss, her new office-mate, and - against every rule either of them just made - the man she can't stop thinking about. When Marlowe & Finch gets absorbed by Cole Structural Group, architect Sunny Marlowe loses her father's name off the door and gains one infuriating, insufferably competent new rival: Adam Cole. Forced to share an office, co-lead the firm's biggest pitch in a decade, and compete for the one promotion they both want more than anything - falling for each other was never part of the plan.
But somewhere between the territory wars over a pencil cup and a storm that knocks out the power, Sunny starts seeing the man underneath the control, and Adam starts seeing the strength underneath the sunshine. Neither of them can afford to lose the promotion. Neither of them can afford to lose each other, either. When old fears threaten to tear apart everything they've built - professionally and personally - they'll have to decide if trust is worth the risk, or if some walls are safer left standing.
The Merger Clause is Book 1 in the Marlowe & Cole series - a slow-burn, grumpy x sunshine, enemies-to-lovers romance with a guaranteed happily ever after.
