Honestly, the reading order debate for Zapata's books is a bit overblown. They're all standalone. That said, if you want the subtle crossover cameos, publication order makes sense. Start with 'The Wall of Winnipeg and Me' just to get her style—it's her breakout hit, so it's a safe entry point. Then 'Kulti'. After that, maybe 'From Lukov with Love' for more sports romance vibes. I jumped straight into 'Kulti' and didn't feel lost at all; Sal's grumpiness is a legend for a reason. The tiny references to other characters are fun but not essential.
I'd skip saving 'Kulti' for last, like some suggest. It's often considered her best, so if you start with something weaker, you might not stick around. Dive into the one that calls to you. The only real order is to maybe read 'Wait for It' after 'The Wall of Winnipeg' because there's a direct connection, but even that's flexible.
My friend read them completely backwards and still adored every one. So yeah, don't stress it too much.
