The Road to Roswell is a wacky novel that becomes increasingly endearing as we get to know the leading characters. When the novel started, I worried that it was maybe too humorous, but while reading the final pages, I didn't want it to end. Willis invokes tropes that play well together, romantic comedy, road trips, cosmic mistaken identities, to weave a story that is more about the journey than the destination.  I would recommend this book to readers who have a sense of humor, and are looking for a light science-fiction novel that is both entertaining and rewarding.
