Set in the same sci-fi universe as A. B. Carolan’s The Secret Lab, this new young-adult sci-fi mystery explores a Jupiter-sized planet’s satellite in a faraway solar system where human scientists are studying local flora and fauna but behaving badly until a teen who wants to study the satellite’s ETs comes along. She shows that cooperation is better than xenophobia. In the process, she discovers that the ETs’ beliefs go far beyond ancestor worship.
