I highly recommend this book for fans of Seanan McGuire's In Cryptid series. The blend of mythical fantasy and not-so distant-futuristic sci-fi is hands down one of the best I've ever run across. There are no space ships, but there are self driving cars and cell phones that would not be out of place on Stark-tech shelves. It also gets bonus points because Julius and Co are actually based on Mexican and Central American mythology instead of the more common European or Asian dragons.
