Filthy Liar by Ainsley Booth

She’s a liar. He’s a cheat. Nothing will ever be the same again.

Jason:
It’s been a long, lonely five years. I never stopped caring for Ellie, even after I realized she’d conned her way into our firm in order to get a scoop. Now that she’s back in my life, we have a lot to catch up on—even as the world burns around us, I’m going to find a way to prove she can trust me.

Melinda:
I’m not his Ellie. I never was. She doesn’t exist, and if Jason starts digging into Melinda the journalist, that won’t end well for me, either. But now that some of our cards are on the table, maybe I can use Jason one last time. For the greater good.
