Aliens in Disguise
by Clete Barrett Smith
Recommended Ages: 10+
Fans of the series will probably best remember this book as the one in which the kids and their extraterrestrial guests mount a daring rescue of one of their own by parading through town, pretending to be science-fiction fans disguised as aliens. But the disguise theme cuts the other way, as a loopy couple of UFO hunters tries to pass as Mr. and Mrs. E.T. and later, many of the characters attempt another costume act that you have to read to believe. The weirdness is funny and the humor is weird, and a bit of youthful romance makes a nice garnish to a very light but charming adventure in the often overlooked hospitality side of science fiction.
Besides this trilogy, which also includes Alien on the Rampage, Clete Barrett Smith is also the author of Magic Delivery (about a load of magical Halloween costumes that turn the wearers into whatever they are pretending to be) and Mr. 60% (about a high school drug dealer with a heart of gold). I'm reading the former right now. But I wouldn't mind seeing more books in this series, populated with goofy aliens, goofier humans and two very resourceful kids.
