A novel about growing up … and blowing up. Mara Carlyle's senior year is going as normally as could be expected, until- wa-bam!-fellow senior Katelyn Ogden explodes during third period pre-calc. Katelyn is the first, but she won't be the last senior to blow up without warning or explanation.With the whole country watching, the FBI soon rolls into Mara's suburban New Jersey hometown and the search is on for answers. 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 ButtonTM” and the filthiest language you've ever heard from the president of the United States. Aaron Starmer defies every rule in 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 twenty-first century-and the heartache of saying good-bye. Ages: 15+ 'Aaron Starmer skillfully welds sharp humor, deep loss, and roaring escapades. Truly the smartest and funniest book about spontaneous combustion you will ever read.' – John Green, #1 Bestselling Author of THE FAULT IN OUR STARS 'This is an invigorating ride because it's not just iconoclastic, not just in-your-face, but smart too, and highly entertaining.'
