I'd never heard of Norah McClintock, but I should have. She writes YA mysteries and, if this one is any indication, they're fast, fun, and surprising!
About that Night is a book that mostly focuses on the disappearance of a popular teenage boy one cold night after Christmas. However, the same night that Derek disappears, a popular high school teacher Elise also disappears. Is it just an unlucky night, or are the two related? Elise is found relative quickly and her disappearance is explained relatively quickly. But Derek's lingering disappearance becomes the mystery of the story.
Jordie, Derek's girlfriend, and the reader know more than the cops for a majority of the story. There are little details to which we are privy, and yet it's not obvious. While Jordie is trying to solve the mystery and save the lives (or quality of lives) of the potentially innocent, so is the reader.
The pacing of the book is fast and energetic, constantly presenting a new theory, hitch, or clue for the reader to chew on. The characters, while not particularly likable, are relatable and feel like normal people in extraordinary circumstances.
The ultimate resolution.... well, you'll have to read it to find out. But I will say I ended the book and my first thought was "whoa." So I recommend to anyone looking for a quick mystery to pass a few hours. (And I note that I didn't think the fact that it's a YA detracted at all from the mystery.)
