Ninja Cyborg

Book 155 in the Choose Your Own Adventure series drops you into a dojo under threat from a part-human, part-robot ninja who has traveled from the future to steal sacred scrolls. The combination of martial arts and science-fiction time travel is an unusual genre mashup, and the branching structure does what the series does best — it puts real decisions in the reader's hands and rewards coming back for different paths. Short chapters make it a good pick for reluctant readers. The honest caveat: characterization is thin by design, and the time-travel premise can feel at odds with the ninja setting. This is a perfectly competent series installment rather than a standout entry, but fans of the format and the genre combination will find it fun and easy to finish.
