Now a new motion picture starring Katherine Langford, Charlie Plummer, and Hayley Law!

“Truly the smartest and funniest book about spontaneous combustion you will ever read.” (John Green, number-one best-selling author of The Fault in Our Stars)

Mara Carlyle's senior year is going as normally as could be expected, until - wa-bam! - fellow senior Katelyn Ogden explodes during third period precalc. 

Katelyn is the first, but she won't be the last teenager to blow up without warning or explanation. As the seniors continue to pop like balloons and the national eye turns to Mara's suburban New Jersey hometown, the FBI rolls in, and the search for a reason is on. 

Whip-smart and blunt, 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, "Snooze Button™", Bon Jovi, and the filthiest language you've ever heard from the president of the United States. 

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. 

“Wildly inventive.” (Entertainment Weekly “Must List”)

“A comically surreal novel that will blow your mind.” (People Magazine)
