Ionic and covalent bonds are a piece of cake for MJ. But human bonds are a little harder ...There are only two things MJ wants in her final year of high school: 1) Glowing grades and ...2) to convince uber-smart, chiselled-jaw Jason they'd be a winning team outside the science lab as well as in.Tutoring deadbeat drummer, Luke, isn't part of the plan. After all, he has average intelligence, takes disorganised notes and looks like a partied-out zombie at their study sessions! Not even his taut biceps will win MJ over.But MJ learns that she could be tutored in a few life lessons too: That sometimes there's good reason to skip chemistry tutorials. That intelligence is so much more than a grade average.And that sometimes you can't beat the chemistry.

Love curses don't exist. At least that's what Jonas, master of the meaningless hookup, tells himself when a letter warns him he's an Eros Guardian cursed to endure a test of true love or forever be alone. His levelheaded longtime friend Cora figures it's a revenge prank by an ex. The way Jonas stamps each girlfriend with a weeklong use-by date, it serves him right. But when an impulsive kiss between the two friends reveals potential for more, Cora becomes the target of the Groth Maar: demons sent to wipe out the Eros Guardian line. And suddenly the curse becomes dangerously real. Breaking the curse means Jonas's biggest challenge yet. Failure guarantees Cora's death. But success may cost him his own life...and the loss of his carefully guarded heart to the one girl far too sensible to fall for him.
