Book Review: Mr. Wrong Number by Lynn Painter

If you’re into flirty texting, chaotic girls, and brother’s hot best friends who maybe catch feelings, then Mr. Wrong Number needs to be your next read.

Olivia Marshall is clumsy, messy, dramatic (in the best way), and totally lovable. After accidentally setting her apartment on fire—yes, literally—she ends up crashing with her older brother and his ridiculously attractive (but annoyingly perfect) best friend, Colin. Awkward, right?

Things get really interesting when Olivia starts texting with a mystery guy—her “Wrong Number”—and the texts turn into a full-blown flirt-fest. What she doesn’t know? Her secret texter might be someone way closer than she thinks.

Colin Beck is Mr. Responsible. He’s neat, serious, and 100% not ready for Olivia to explode into his calm little world. But the more time they spend together, the more he realizes her chaos might actually be kind of… adorable? And just when he thinks he’s falling for the girl he’s been texting, he finds out she might be under his roof.

This book made me actually laugh out loud. The banter is fast and fun, the chemistry is “chef’s kiss”, and the dual POV makes it so fun to watch them both fall for each other without even knowing it. I loved how over-the-top and ridiculous it was at times (in the best rom-com way possible), but it still felt real enough to get totally hooked.

🔞 Recommended for 14–15+ readers because of a little mature language, swoony scenes, and steamy vibes—but nothing super graphic.

⭐ My rating: 5/5. I’ve reread it three times already and I’m still obsessed. The characters? Adorable. The texting? Flirty perfection. The ending? So satisfying.

📚 If you love dual POVs, slow-burn romance, and chaotic-good main characters, this one’s for you. Similar authors: Carley Fortune (Every Summer After), Sarah Adams (The Rule Book, C.W. Farnsworth (Kiss Now, Lie Later)
