John Scalzi's standalone novels

Starter Villain

by John Scalzi

John Scalzi brings us a turbo-charged tale of a family business with a difference, as Charlie discovers when he inherits it. It’s also way more dangerous than Charlie could ever have imagined, because his uncle had kept his supervillain status a secret. Divorced and emotionally dependent on his cat, Charlie wasn’t loving life. Now Charlie must decide if he should stay stuck in his rut, or step up to take on the business, the enemies, the minions, the hidden volcano lair. But there’s much more to being an Evil Mastermind than he suspected. Yet could this also, finally, be his chance to shine?

Known as the 'Kaiju Preservation Society', Jamie unwittingly signs on with Tom to venture to the Earth of an alternate dimension, where massive dinosaur-like creatures called 'Kaiju' roam a human-free world. But they’re in trouble – the Society are not the only ones who have found their way to the Kaiju world. . .
