Newton couldn't predict this love equation—but one student's probability data did. EDWARD Teaching physics at Clear Creek High suits my perfectly ordered life - or at least it did until I volunteered to lead the robotics team. Now I find myself looking forward to every workshop, and not just because our robot housemaid prototype is finally learning to spray tables instead of students. It might have something to do with Angus' mother, Sophie, who signed up as a volunteer to help her son on the spectrum. I've never met anyone quite like Sophie. She gets my science jokes, understands my passion for teaching, and somehow doesn't mind when I geek out about physics principles. But just as I'm gathering the courage to ask her out (and finally give Angus the data points he keeps requesting for his romance probability spreadsheets), her ex-husband announces he's moving in next door to "be more involved." Now he's threatening custody changes if Sophie dates me. The logical solution would be to maintain professional distance. Except Angus has already calculated our compatibility rating (apparently we're a 94. 3% match), and the entire town seems invested in our hypothetical relationship - especially Mrs. Baxter, who's probably already booked a wedding venue. With the state robotics finals approaching and Angus documenting everyone's "emotional variables" in yet another color-coded chart, I'm discovering that some equations can't be solved by science alone. Though according to Angus' latest statistical analysis, there's a 97. 2% chance I'm overthinking this. For fans of sweet romcoms and witty banter, "The Love Variable" is a must-read. If you enjoyed "The Rosie Project" or are a fan of Sarah Adams and Emma St. Clair, you'll love this sweet and clean novel. Buy now before the price changes!
