From advice columnist Meredith Goldstein, a dazzling, romantic, and emotionally resonant YA debut about a teen science whiz in Cambridge, Massachusetts, who tries to crack the chemical equation for lasting love and instead wreaks havoc on herself and the boys in her life. For seventeen-year-old Maya, the equation for happiness is simple: a dream internship at MIT + two new science nerd friends + a perfect boyfriend = one amazing summer. Then Whit dumps her out of the blue. Maya is miserable until she discovers that her scientist mother, before she died, was conducting research on manipulating pheromones to enhance human attraction. If Maya can finish her mother's work, maybe she can get Whit back. But when her experiment creates chaos in her love life, she realizes that maybe love and loss can't be understood using the scientific method. Can she learn to trust the unmeasurables of love and attraction instead?

A steampunk princess is torn between love and duty in this prequel to SyFy.com’s wildly popular webisodes. Riese has never been happy as a princess; she’d much rather be hunting or fighting than sitting through another lesson on court etiquette.

But with war decimating her once-proud nation and the sinister clockwork Sect infiltrating her mother’s court, Riese’s moments with Micah are the only islands of sanity left in a world gone mad. As her kingdom falls and the Sect grows ever stronger, will Riese remain true to her duty as a princess…or risk everything on a boy she barely knows? SyFy’s enormously popular Riese webisodes come to literary life in this prequel rife with steampunk technology and medieval mysticism.
