Connor and Logan have been best friends since kindergarten. Now in their third year of university, sharing an apartment feels as natural as breathing?easy, comfortable, and safe. Until the day Connor comes home and finds a tall, broad-shouldered stranger laughing with Logan in their living room.

The stranger turns around.

It's Shaun?Logan's younger brother, the kid who moved away years ago and barely feels like a memory anymore. Only now he's grown, confident, and devastatingly handsome. And the looks he keeps giving Connor? They definitely mean something.

When Shaun comes out, Connor realizes the truth: the sparks between them are real?and dangerous. Logan has no idea Connor is gay, and definitely no idea what's building between his best friend and his brother. One weekend under the same roof is all it takes for temptation to win, and for lines to be crossed that can't be uncrossed.

Because some feelings don't fade. Some connections don't break. And some mistakes are anything but forgettable.
