A Man of Prestige by S.E. Rose

Billionaire Doctor Aiden Thomas doesn’t give second chances, but Estella Garcia might change his mind, and his heart.

Aiden Thomas and his closest friends have come across a drug that may be responsible for the deaths of young women in the city. When he obtains a sample of the drug, he needs it analyzed, and there’s only one person he knows with access to the technology to do it, his ex, Estella Garcia.
Estella has worked her way back from a life-shattering event. She’s finally moving on after years of heartbreak until the man who destroyed her comes walking back into her life.
Estella’s discovery leads Aiden to look for an enemy amongst the members of a secret society that he vowed to protect. In a city full of powerful men who will stop at nothing, everyone is a suspect. These two are about to find out that nothing is as it seems, and no one can be trusted.
