Paradox by JJ Asher

I know now, for certain, that I’ve made a deal with The Devil. I’m just not sure yet if I’ve sold him my soul as well.

Jintae—nineteen, desperate, and done letting his parents script his life. His brilliant escape plan? Drop out of college and vanish into the wilderness, hiding in the off-grid cabin of his brother’s best friend until the storm blows over.
The problem? That best friend is running too.

Eden—thirty-four, newly single, and in no mood for company. Especially not the perfectionist teenager with too many brains, and too little sense, that’s always gotten under his skin.
He craves solitude.
Abandonment has hollowed him. Heartbreak has left him bitter and violent. So when Jintae shows up uninvited, he throws him out—until the kid begs. He offers himself up as a live-in servant, and Eden agrees… On brutal terms.

But what started as punishment soon turns into something Eden can’t name. Jintae challenges him, haunts him, tempts him. Under the fury is heat. And under the insults is a pull neither of them can outrun.

Snow traps them. Secrets rot between them. And the boy Eden swore to stay away from becomes the one thing he can’t stop craving.
