Robin Hood, 1192 (The Symbiont Time Travel Adventures Series, Book 7‪)‬

Petra and Kipp, accompanied by fellow time travelers Peter and Elani, travel to medieval England to answer a nagging question in the time-travel adventure, Robin Hood - 1192, by T.L.B. Wood

Was Robin Hood a real man or a myth?

The ever-curious time traveler, Kipp, becomes intrigued with this question after reading the novel, Ivanhoe. He convinces his partner, Petra, that a trip to medieval England's dangerous and politically complicated times is necessary to solve the puzzle.

Accompanied by fellow travelers, Peter and Elani, the team assumes disguises as humans partnered with their companion dogs. But the class conflicts between the conquering Normans and the native Saxons quickly turns the adventure into the most dangerous feat the four investigators have undertaken.

Now the travelers face a new question: Can they find the way back to their own time?
