Blind Spot by Olivia Gaines

Mr. Slow took his time in life. Love, family, and the job were functions performed by the man he needed to be. A phone call in the middle of the night transformed him into the man he’d always wanted to be. Everything he ever wanted for himself was within his grasp, but he was reluctant to reach for the happily ever after he craved.
Abigail Barnes was the cherry on top of the ideal sundae. A woman who is not willing to be tied down by any man, for any reason. When her cousin goes missing, she makes the one phone she’s been dreading for nearly five years. She needed to call the man who turned her emotions on end, making her want all the things life didn’t have time to give her, but she needed his help.
Arriving in the middle of the night to help the woman who made him lose sleep, he discovered the two of them shared more than three hot nights in a cheap hotel in Mexico.
Prepare to turn the pages and learn of the man the technicians call Mr. Slow, but also the man, Gabriel Neary, the Archangel, calls his cousin.
