Invisible Girl — Tess Hudson

Surviving a lifetime of her father's secrets, schemes and whispers of veiled conspiracies, Maggie Malone has always felt invisible -- to her father, and to the world who could never understand her. And now she must trace the steps of her ghost-father to find out who wanted him dead.

When Maggie's criminally inclined brother shows up at her apartment in the middle of the night severely beaten, she's certain it has something to do with their father -- a highly secretive, shifty Vietnam vet, always on the run and impossible to know. They haven't heard from him in months, which isn't unusual. But they soon discover that he isn't just missing. He's been killed.

As secrets from her father's murky past are uncovered, Maggie is led back to her family's roots in the flames of Vietnam. Who was Jimmy Malone? What became of a tiny baby girl sent to America in Operation Babylift? And who are the shadowy figures who will stop at nothing to prevent the secrets of the jungle from coming to light, even if it means murder?
