Tracker by Charity Parkerson

Tracker has watched his brothers fall one by one into their happily ever after. Truthfully, they’ve made love look messy. He’ll stick to his computers.
With a shared love of hacking and knowledge, Zeus and Tracker have spent way too many hours together. As the owner of a kink club, Zeus is accustomed to being the most desired man in every room. Plus, he was literally bred to steal hearts. Oddly, Tracker is completely immune to his charms. No amount of time together has led to more than friendship. His disinterest in Zeus has Zeus as intrigued as he is baffled. One way or another, Zeus will crack his shell.
Tracker loves spending time with Zeus. They have a ton in common. Zeus is nice and fun. Not to mention wicked and crazy smart. He’s Tracker’s best friend. Sometimes, Zeus flirts too much, but that’s just who he is. Not that Tracker would know if the guy ever flirted for real. He’s only dated online. Tracker has no desire to change that.
