I thoroughly enjoyed The Humans, which makes effective use of an alien narrator to bring the flawed yet precious nature of human existence into focus, managing as it does so to carry off the difficult trick of being both moving and funny. The list of 'advice for a human' near the end is particularly memorable and uplifting.
The Radleys, which was written earlier but I picked up later, is another fun variation on the not-quite-human theme, about the chaos that ensues when the teenage children of abstinent vampires discover the truth about their family. This allows for witty explorations of themes of teenage identity crises (including some funny asides on veganism), destructive desires, and family secrets. I liked the twists in some of the character descriptions, such as the fact that the most depraved and treacherous vampire had saved his brother's life as a child. The only weak point for me was that it strained credibility to show parents - even vampire parents - and their children enjoying going clubbing together...
