The Teach Me series starts off with the story of Raine and Mac, the most unlikely of best friends... Taken from his parents and bounced from one foster home to the next, former Navy SEAL turned math teacher, Callum "Mac" Mackenzie had a rough childhood. The only time he's let himself get attached to anyone has been with his military "brothers". He's convinced he doesn't know how to love and certainly doesn't "do" relationships. He's spent fourteen years in the Navy and now he gets to live out his other dream: teaching. Her thirtieth birthday fast approaching, science teacher, Raine Thompson feels as if her time to find "the one" is running out. She knows life is short, especially after dealing with breast cancer two years ago, and wants to experience her own happily ever after. But is it in the cards for her? Finally acting on the simmering attraction they have long ignored, Raine and Mac decide to have a fling and they discover what it's like to have someone who knows you inside out also be the one who makes your body come alive. But it was only temporary...
