Kiss Me if You Can (Love in Sun City #0.5)
Dana LeCheminant

Jake finds himself unexpectedly in trouble, and meeting Isla feels like a blessing and a curse. She can help him lie low, but every minute he spends with her puts her in danger. If only his heart would listen to his head when it tells him they should part ways.
When a misunderstanding leads to Isla suddenly needing a fake husband, Jake seems like the perfect option. He can hide in plain sight, and Isla can move forward with her business plans. If only things weren't starting to feel more and more real…
With the FBI closing in, they may just be out of time to see if their instant connection might be more than a fleeting moment. There's no way the fake marriage can end well when both of them have laid their hearts—and maybe their lives—on the line.
