Sphinx by M.E. Clayton

Do secret societies really exist?
The Order of the Cronus does, and as an organization that has stood the test of time, it made a person question what exactly it took to make something like that happen.

Fox:
Reputed to have the makings of a born leader, Fox Harrington was no stranger to taking control of a situation and making it all work out, no matter who thought they were in charge. Born into one of the wealthiest legacies in the nation, Fox hadn’t been naïve to the expectations that had been placed on him at a very young age. Still, Fox was always ready for the next step or the next enemy.
With only one more year left at Hales University, all that Fox had to do was make it through his senior year without mucking things up. The Order of the Cronus had big plans for him, and they wouldn’t take kindly to Fox prioritizing anything before them. Only the most brilliant and powerful could continue to make the organization work, and Fox knew it like he knew his own name.
However, that was all before Kincaid Black came into the picture.

Kincaid:
With her entire future ahead of her, Kincaid Black didn’t have the worry and headaches that most people did. Born into one of the most powerful families in the nation, Kincaid hadn’t been raised to be soft. Still, when a horrible tragedy hits home, she is changed forever. Already a force to be reckoned with, Kincaid becomes something entirely different.
Prepared to make the most of the opportunities afforded her, Kincaid remains focused, determined, and unstoppable. Attending Hales University was more than an educational blessing, it was a personal coup. With her best friend at her side, cowardice a foreign concept, and more money than God, Kincaid feared nothing, and nothing was going to stand in her way for what came next.
However, that was all before she found herself having to choose between her past and her future.
When secret societies really do exist…
Fox Harrington had been prepared to do whatever necessary to win, but when Kincaid Black enters his life, not only does his entire life shift on its axis, but The Order’s foundation is also shaken.

Kincaid Black had not been prepared for Fox Harrington, but when it becomes clear that he isn’t going anywhere, she’s faced with having to break his heart, hers, or both.
Together, Fox and Kincaid find themselves at in a constant struggle with everyone around them, but also with each other, and that’s not a good thing for anyone.
