Mara Carlyle’s senior year is going as normally as could be expected, until fellow senior Katelyn Ogden explodes during third period pre-calc. Katelyn is the first, but she won’t be the last teenager to blow up without warning or explanation. As the national eye turns to Mara’s suburban New Jersey hometown, the FBI rolls in and the search for a reason is on. Mara narrates the end of their world as she knows it while trying to make it to graduation in one piece. It’s an explosive year punctuated by romance, quarantine, lifelong friendship, hallucinogenic mushrooms, bloggers, ice cream trucks, and Bon Jovi.
Aaron Starmer rewrites the rulebook with Spontaneous. But beneath the outrageous is a ridiculously funny, super honest, and truly moving exemplar of the absurd and raw truths of being a teenager in the 21st century . . . and the heartache of saying goodbye.
