After twelve whole years of grueling education, 18 year old Reyna Knight finally graduated at the top of her class from Obsidian River Academy, a private and specialized school that trains high end body guards called Arrowheads. Unfortunately, Reyna's first assignment is a total buzzkill when she is hired by Jay Overland, head of the multi-billion dollar company Overland Enterprises, to protect to the life of his son, Aspen, a typical cocky and rebellious college student. With Aspen being Reyna's first "professional" mission, she can't afford to make any mistakes or complications. All she has to do is go undercover as a college student at his school, and make sure the overgrown twerp stays alive past his 20th birthday. There is only one small problem...Reyna does not know who or what exactly she is protecting Aspen from, and he cannot know that the girl he is totally smitten with is watching over him.
