Start Up in the City Books in Order

Start Up in the City is Kelly Rimmer’s contemporary romance series set against the energy of modern urban life and the tech world. Each book stands alone but follows friends and colleagues whose careers in startups collide with very personal questions about love, commitment and what it means to build a life that actually fits.

In Unexpected, lifelong friends and roommates Abby and Marcus turn a pragmatic co‑parenting plan into something far more complicated when a health scare pushes Abby to have a baby sooner than she ever intended and Marcus quietly realises he wants to be more than the best friend who shows up.

Unspoken shifts the focus to Isabel and Paul, a couple on the brink of divorce who both retreat to their shared Long Island house for one last solitary weekend and instead find themselves trapped together. Over a few intense days, they finally talk about the silences, work obsessions and old hurts that nearly destroyed their marriage, and they have to decide whether to walk away or fight for a different kind of future.

In Undone, high‑powered tech CEO Jess Cohen would rather juggle investors than feelings, especially after cutting off a secret relationship with Jake Winton without ever explaining why. When she returns as maid of honor at her best friend’s wedding and Jake is there as best man, their unresolved chemistry, shared history and Jess’s closely guarded past all crash together in a story about second chances and the courage it takes to be fully known.

Across the trilogy, Rimmer uses the fast‑paced world of startups as a backdrop rather than the main event. The real stakes live in late‑night arguments in tiny apartments, fraught conversations about fertility, trust and money, and the way friends can become family long before anyone admits they’re in love.

The tone is contemporary and modern—there’s witty banter, geeky in‑jokes, and plenty of heat—but the books don’t shy away from vulnerability, therapy and hard conversations. You can read any title on its own, but in order they feel like a small, interconnected universe where each happy ending ripples through the lives of the next couple.

If you’re new to Rimmer through her historical novels, this series shows a lighter side of her work while still carrying emotional weight. The books offer steamy scenes and big romantic gestures, but they’re also about chosen family, mental health and the way love can grow in the least convenient moments.
