She coded walls around her heart-he's about to hack every one.

Anna Chang has three rules: trust no one, never skip a coding sprint, and absolutely, under no circumstances, fall for your brother's best friend. Especially when that best friend is Joel Price-charismatic rockstar, smug heartbreaker, and the guy who under no circumstances can be trusted.

Now he's back. And worse? He's sleeping in her guest room.

With forced proximity, a family event from hell, and the entire Dirty B's book club egging them on, Anna's perfectly curated life is about to be debugged in the messiest, steamiest way possible.

Enemies-to-lovers? Check. Brother's best friend? Unfortunately. Still wants to kiss him? Absolutely not... probably.

Welcome to Dirty Developments-where the only thing more dangerous than catching feelings is letting them crash your firewall.
