Thorns: When Earth Refugees Are the Aliens

Siddhartha, known as Siddie, and his parents joined a small group of families leaving Earth to colonize a distant planet. To Siddie, a curious 13-year old with a knack for getting into trouble, the journey is a grand adventure. But his parent's reasons for leaving Earth are a mystery. Eventually, he's going to have to learn the truth.

Blue belonged to a species calling themselves kodrya (ko-drya). Kodrya society, known as Phyleem, had one zin (i.e., rule): all kodrya must grow thorns. Unbeknownst to Blue, Earthlings were orbiting her world and preparing to land. One in particular, named Siddie, would change her destiny.

Kirkus Reviews
In Kahn's debut SF novel, Earth's plan to colonize a distant planet collides with the Indigenous beings already living there. A succinct outer-space romp that entertains as effectively as it educates.
