Had high hopes for this one. If you liked Anathem you would probably think this one is a masterpiece. I just found it strained too hard to try to be creative, between the technology and the complicated aliens and such. The beginning captured my imagination but from there it just went bizarre and required way too much work to visualize the creatures, places, and story. I dropped out after about 5 hours. Couldn't take it anymore ... paying for another download and wasting this credit was better than the pain of continuing to listen and scratch my head. Use a credit on this one at your own risk.
