Artemis Fowl II is superb with prep time. He literally stopped a black magic crazed pixie with an army of undead soldiers in under a day with little prep time and most of it was done while trying to not be killed. He managed to escaped a time field which was never done before nor even known how to do it by the people who invented it. If you want a full account of his accomplishments then read the book series Artemis Fowl by Eion Colfer
