Mi Sweethart is easily the worldâs greatest secret agent; itâs really no contest. But a holiday would be nice, so for the first time since she was eighteen, Mi is taking a break⌠or she would be if it werenât for the sword-wielding assassin in her back garden. Thanks to Miâs unihemispheric sleep pattern (itâs a real thing, look it up!), Mi never has to stop. While some would squander this extra time watching acclaimed TV drama, Mi has spent it becoming the best at everything, but will being the best be enough for whatâs coming?
