Johnathan Rand deserves some credit for not settling into a rut, but Alien Androids Assault Arizona is probably the most bizarre of the first sixteen American Chillers. Fifth-grader Shelby Crusado's best friends—Arielle Watkins and Joey Romaniello—moved to Scottsdale, Arizona within the past few years, but they feel like a lifelong trio. So Shelby naturally goes to them after she overhears Mrs. Rodriguez, their schoolteacher, speak in a robotic voice into a device on her wrist. Arielle and Joey laugh at Shelby's insistence that their teacher is a robot in disguise, but Shelby spies on Mrs. Rodriguez a few more times and becomes convinced the woman isn't human. When Mrs. Rodriguez catches her, she isn't angry; she seems amused by Shelby's accusation, and in her ordinary voice tries to reason with her that she couldn't possibly be an android. Wait...android? Shelby never used that word. She feels more sure than ever that Mrs. Rodriguez is an artificial life form, and Shelby takes a big risk to gather evidence of what she's overheard her teacher say in her robot voice: that she is an android acting as liaison for an alien race bent on stealing all of Earth's water. If Shelby can't convince people the threat is real, space invaders will take over her home planet.
Arielle continues to scoff, but Joey reluctantly agrees to take Shelby seriously. When he accompanies her to spy on Mrs. Rodriguez at home, he hears their teacher speaking in the robot voice; now he knows Shelby wasn't spinning a sci-fi fantasy. The android mentions that the "master plans" for conquering Earth are hidden in her garage, but swiping them turns out to be harder than expected, so Shelby and Joey opt for another angle: find Mrs. Rodriguez's spaceship at a nearby warehouse, and fly in it to her planet of origin, 430-X. There's more at stake than learning about the aliens' strategy to invade Earth: Mrs. Rodriguez apparently suspected that Arielle was on to her scheme, and had her abducted and sent to 430-X, light-years away from Earth. With courage and an extraterrestrial spacecraft as their only assets, Shelby and Joey go hurtling across the universe at warp speed. Mechanical failure and encounters with hostile aliens threaten to permanently strand Shelby and Joey in deep space; however, if they reach 430-X and return to Earth before the aliens invade, they have a vague hope of thwarting the enemy. But has the android infiltration progressed further than Shelby knows?
Alien Androids Assault Arizona is difficult to assess. The sci-fi aspects are way over the top, but represent more originality than usual for Johnathan Rand. He even attempts a few plot twists, convoluted though they are. Ultimately, Mr. Rand outsmarts himself with too many zigzags; the story gets crushed under the weight of its own implausibility. I enjoyed the brief literary conversation on page twenty between Shelby, Arielle, and Joey: Sheila Burnford's The Incredible Journey and Gary Paulsen's Hatchet are worthy subjects for a book report. It's also notable that the print size in Alien Androids Assault Arizona—the edition I read, at least—is smaller than for previous books in the series. The story goes one hundred ninety pages, a bit longer than normal, so that probably means it has a higher word count than any of the prior fifteen books. I'll bump Alien Androids Assault Arizona up to one and a half stars, but it's one of the lesser American Chillers to this point in the series. Still, I found it entertaining.
