Jacqueline’s Quest by TL Reeve

When Murray Jacobs’, resident hacker for R.O.O.T, parents died in a horribly tragic accident, he became the guardian to his little sister. He did everything he could to protect, especially after a rare sickness took her ability to use her legs.
Then, one day, she disappeared.
Jaqueline “Rainbow” Herrera, ex Mexican Special Forces better known as Cuerpo de Fuerzas Especiales, came home after her parents died to care for her brother Christian who is autistic. When he goes missing, she willingly re-enters the underground world of the Mexican Cartels—more specifically the Nieto Cartel and the Emporio de Monstruo.
Hannah and Christian’s lives are in the balance as the auction begins.
Murray and Jaqueline must place bids in order to save their siblings to keep up appearances. However, when the cartel finds out they’re not who they say they are, will Murray and Jaqueline be running out of time?
