I have a giveaway this week, but I’m going to end it on Wednesday, Feb. 14. That gives me a couple days to get to the post office. I just wanted to point out the deadline so you notice it, if you’re interested in the books. Both books are about romance and STEM.

Let’s start with Mike Chen’s A Quantum Love Story. The only thing harder than finding someone in a time loop is losing them.
Grieving her best friend’s recent death, neuroscientist Mariana Pineda’s ready to give up everything to start anew. Even her career—after one last week consulting at a top secret particle accelerator. Except the strangest thing happens: a man stops her…and claims they’ve met before. Carter Cho knows who she is, why she’s mourning, why she’s there. And he needs Mariana to remember everything he’s saying. Because time is about to loop. In a flash of energy, it’s Monday morning. Again. Together, Mariana and Carter enter an inevitable life, four days at a time, over and over, without permanence except for what they share. But just as they figure out this new life, everything changes. Because Carter’s memories of the time loop are slowly disappearing. And their only chance at happiness is breaking out of the loop—forever.

Maybe you’d prefer Sara Read’s Principles of (E)Motion.

Mathematical genius Dr. Meg Brightwood has just completed her life’s work—a proof of a problem so impenetrable it’s nicknamed the Impossible Theorem. Reclusive and burdened by anxiety, Meg has long since been dismissed by academia. Now everyone wants to get their hands on what she alone possesses—especially her own mathematician father. Having grown up a prodigy in a field plagued by sexism and plagiarism, Meg opts for a public presentation so there will be no doubt of her authorship. But a panic attack obliterates her plans. In defeat, she goes home and locks away the only manuscript of her proof. Then chance sends her the unlikeliest of allies: Isaac Wells—carpenter, high school dropout, in trouble with the law. And the one love of Meg’s life. Fifteen years ago, they did little more than hold hands. Now, they find a tenuous space where they can love and be loved for who they are as adults. But when Meg goes to retrieve her proof, she finds it missing. Her fight for the achievement of the century will test the limits of her brilliance and the endurance of two vulnerable hearts.
