From This Day Forward by Ketley Allison

Somebody is lying…

It’s official–and what a cliche–but I’ve been dumped. By my high school sweetheart. Over a dick pic.
Then HE walks into my life, the guy three rows and two seats in front of me, the dude who can’t stop getting A++ and smiley faces from the professor and every lady that passes him by. Mr. Know-it-All with the sexiest quirk to his lips and whose talents extend well beyond simple English exams.

Spencer Rolfe is better left untouched. But when he offers to tutor me, I can’t say no. I must get my grades up and he’s the smartest guy around. At least, that’s what I tell myself. But the more I get to know Spence, the less sure I am, and soon Spence’s mysteries become irresistible.
And little do I know, but someone else finds me irresistible, too.
And he waits in the dark.
