the story is told from nyssas perspective presumably a while after shes left the tardis in the future, and its got a very depressing vibe. theres some really cool moments like her literal death but i feel like the dar traders are undeveloped and its not really overly explained what their exact purpose is. the story takes a weird turn in the last 15 minutes as well and none of it really meshes well with other elements of the story. not the best companion chronicle.
