Reverse harem, guys in private security named Jackson Knox and Theo

[Lindsey]

Read maybe a year ago, can not remember the other guys names or the leading lady, but I believe there was five guys total. She lived with her dad in hiding, there was an explosion and the guys found her and helped her find her dad. She was training to join there security firm, when she was kidnapped again. Pretty sure Jackson had a dog named penny and lived on the beach. That is all I’ve got please help!!!
