After the Saucers Landed [Lain, Douglas]

Shape-changing aliens may have landed on the Whitehouse lawn and subsequently integrated into human society, but humanity is still full of self-centred and self-absorbed individuals. Laura's just scraping by on her art teacher's salary. Donald, a bestselling author and UFOlogist who provided counselling to abductees, has tried to distance himself from the saucer landings and is looking to move on with his life. But everything changes when Shelly, an alien enrolled in Laura's art class, mysteriously switches places with Laura.
