Everything's changing for our friendly neighbourhood serial killer. As if getting married wasn't enough to complete his nice-guy persona, Dex is now the proud father of a baby girl. And disconcertingly, he actually seems to care. But even if fatherhood is distracting Dexter from his midnight excursions to rid Miami of a few more lowlifes, there's no let-up at work. Two young girls are missing - and it's not long before one of the bodies turns up, partially eaten. But as Dexter and Miami PD's finest investigate, Dex can't shake the feeling that somebody's watching him...At home, there's no rest for the wicked. His stepchildren are clamouring to learn how to control their bloodlust and Dexter must train up his young apprentices. But to do that, he'll have to find the missing girl, find out who's tailing him and survive a dark journey into a underground community who really have a taste for death.
