Some summers change everything.Some men are supposed to be off-limits.Desmond Cole is both.Anna Ashford has spent nineteen years being the good daughter — the one who smiles at the right moments, laughs at the right jokes, and pretends not to notice the way her father's best friend looks at her when he thinks nobody is watching.She notices.She has always noticed.But noticing is not the same as acting. And acting is not the same as falling. And falling —Falling is something else entirely.One night at the lake house changes the rules of every game Anna thought she understood. Desmond is older, powerful, and completely wrong for her in every way that counts. He knows it. She knows it. And the lake outside her window knows every secret they are trying to keep from the man sleeping down the hall.He calls it a mistake.She calls it the most honest thing that has ever happened to her.And now neither of them can find their way back to who they were before it.The Devil's Lake is a story about wanting what you cannot have, taking what you should not touch, and discovering that the most dangerous fires are the ones that feel exactly like home.Some mistakes you survive.Some you choose, again and again, until choosing becomes the only truth left.
