The Mercenary's Daughter

When Special Ops recruit, Tara Kafee is dishonorably discharged, there's only one place to go-Home. But there's more waiting for her there than she's ready for. It's been four years since she's been back and ten since her mother walked out on the family never to be heard of again. She's determined to rekindle things with her father and keep him close. That is, until he goes missing. Soon after stumbling upon a safe room full of weapons, fake passports, and a mission's dossier marking a target in Cuba, she reluctantly accepts the help of her angsty teenage brother.
He's the only one she can trust, so together, the two set out for Havana. Tara is determined to get her father back, whatever it takes, but things are never easy when you're the mercenary's daughter.
