Francie is a reluctant Maid of Honour, for several reasons. The first is that her friend Serena has terrible taste in men. Previous fiancs have included a storm-chaser, a shaman and a kamikaze base-jumper. This is the closest a wedding has come to happening, and it’s to a UFO-chaser. The second is that, as a result, the wedding is being held in New Mexico. In Roswell. During the UFO festival. After a series of travel disasters that end with her car sharing with another wedding guest – who also happens to be an FBI agent – a wedding due to take place in the UFO Museum, conducted by a high priest from the Church of Galactic Truth, and a frankly repellent bridesmaid dress, the alien abduction is actually a high point of Francie’s day. Bundled by an alien into an SUV, what follows is a chaotic road trip, picking up other waifs and strays, hotwiring an RV, and desperately trying to work out what their alien captor wants.
