Doubt

Sinners and Saints #4

by Kathy Lockheart

I killed a man.

That’s what they charged me with after finding me in the woods with a bloody knife, a dead body, and no memory of how I got there.

The case was over before it began…
until Ryker Kincaid stepped in.

Chicago’s most ruthless defense attorney.
My brother’s best friend.
The only man I ever loved.

He shouldn’t touch me.
Shouldn’t move me into his penthouse.
Shouldn’t look at me like I’m something worth saving.

But he does.

Ryker believes I’m innocent, and he’s risking everything to prove it.
His career. His reputation. His heart.

The price he demands is the truth.
Every secret. Every dark corner of my past.

But I learned a long time ago that honesty makes people leave.

I survived them all walking away.
I won’t survive losing Ryker.

So when the truth finally surfaces, there’s only one question

Will Ryker choose to stay…

or will I lose the only man who ever made me believe I was worth loving?
