Allison Avery has been accepted into her dream Ph.D. program, studying under a professor she's admired for years. Sure, grad school isn't easy, but she's got this. Until she discovers her ex-boyfriend has also been accepted. Colin Benjamin might be the only person who loves winning more than Allison does. What starts as a battle of wits between them turns into all-out war when their professor announces a career-changing research opportunity - with one spot to fill. But when a family emergency and a late-night road trip throw them together for a weekend, Allison will have to choose between a once-in-a-lifetime opportunity and what could be a twice-in-a-lifetime love.
