Sweetest Hate by Baylin Crow

Kellan—Messing around with Arsen is like playing with fire and I can’t help but crave the burn.
The day I met my best friend’s new stepbrother I fell into hate with the moody jerk. The feeling is mutual. I loathe him and unfortunately want him in equal measures. At least he seems to be suffering the same undeniable pull. He infuriates me. He’s crawled under my skin.

Arsen has the ability to ruin me for anyone else, and I want to let him.
A mix-up during a trip to the lake puts us in an inconvenient situation where we end up sharing a room. Worse, once we get home, I’m left unable to escape him. He’s right next door and impossible to ignore. As we spend time together, I’m forced to realize there’s so much more to him than I expected. I thought I had feelings for my best friend, but Arsen has me questioning everything I know about love.
It’s the sweetest hate, or maybe it’s something else entirely.

Sweetest Hate is the second book in the Guys Next Door series and can be read as a standalone. It’s about two guys who may not hate each other as much as they thought. Maybe it’s the opposite. Maybe they can teach each other exactly how to love.
