4. Enchantment by Orson Scott Card
If your guy likes Ender's Game, and you like fairy tales, both of you will love Orson Scott Card's adventurous novel about a graduate student who finds himself stuck in the tale of Sleeping Beauty after he accidentally wanders into an enchanted Russian forest. Once there, he meets a Russian princess, who in turn gets stuck in the modern world after the student unsticks himself from hers. If it sounds anything like Disney's Enchanted, worry not, Orson Scott Card's novel takes a much darker, more adult approach to the same concept. Perfect for a summer night!
