"Days after famed mathematician Isaac Severy dies in an apparent suicide at his Los Angeles home, his adopted granddaughter, Hazel - owner of a struggling bookstore - receives a letter from him. In it, Isaac alludes to a secretive organization that is after his final bombshell equation, and he charges Hazel with safely delivering it to a trusted colleague. But first, she must unravel a series of confounding clues Isaac hid in a copy of her favorite novel - a posthumous puzzle she suspects will lead her to his mathematical treasure.

Hazel is far from the only one searching for Isaac's life work, and as she widens her search, she realizes that the equation has potentially disastrous consequences for the extended Severy family, a group of geniuses unmoored by the sudden death of their patriarch.

As agents of an enigmatic company shadow Isaac's favorite son - a theoretical physicist - and a long-lost cousin mysteriously appears in town, the equation slips further from Hazel's grasp. When her efforts fall short, she is forced to emlist help from those whose motives are not as pure as her own.

A witty and suspenseful mystery, The Last Equation of Isaac Severy proves that, like Hazel, you don't have to love math to fall under the Severy spell."
