Rule #1 of apartment hunting: make sure your new roommate is actually a dude before signing the lease.



Cal Brady failed that step spectacularly.



He’s the Brady who always seems to mess up in memorable fashion. Sure, he’s charming and knows his way around an engine. But the Brady family values precision, reliability, and competence — and Cal’s spent most of his life feeling one step behind the benchmark.



Logan Miller knows exactly where she fits. She clawed her way into a career she built from scratch, and taking on a roommate is the most efficient solution to an inconvenient cash crunch.



Unfortunately, the roommate who answers her ad is an infuriatingly charming engineer with a habit of spilling cereal all over her clean counters.



Cal should not be fantasizing about Logan’s color-coded calendars while trying to prove himself at work. And Logan definitely shouldn’t be looking forward to late-night conversations with the chaos demon currently occupying her spare bedroom.



But somewhere between takeout dinners, partner pedicures, and a living arrangement spiraling wildly out of control, they both start wondering if there’s room in their carefully planned lives for each other.



Margin of Error is a steamy romantic comedy featuring accidental roommates, opposites-attract tension, and two people discovering they might already be enough. Meet the Brady family: they’re brilliant, brooding, and barreling into relationships they never saw coming.
