De la Cruz (Gates of Paradise, 2013) and her husband begin a new series that focuses on environmental catastrophes—specifically, a new Ice Age. Their imaginative vision includes New Vegas, the frozen wasteland that's all that's left of the former city. Here, where casinos and corruption reign, 16-year-old Nat Kestral works as a blackjack dealer and card counter. She has heard of a mythical paradise called the Blue, and she hires a dashing young mercenary, Ryan Wesson, to take her there. But passage to the Blue is treacherous and danger lurks around every corner!
