The Robot Twins by J.R. Rain consists of two children’s adventure novels. The Mystery of the Walking Statue (2011) and The Secret of Stonehead Island (2015) follow twin siblings on science-fiction-tinged adventures.
The Mystery of the Walking Statue opens the series with a puzzle involving a statue that appears to move on its own. The Secret of Stonehead Island takes the twins to a remote island where they face new mysteries. Both books blend science fiction ideas with the kind of clue-based adventure stories that young readers enjoy.
J.R. Rain is better known for his adult paranormal fiction, particularly the Vampire for Hire series, so Robot Twins represents a different side of his writing. The four-year gap between the two books suggests this was a side project between his more prolific series output.
