Fatropolis

Most of her life Jenny has felt she's not good enough, not attractive enough, because she's fat. Then one day she stumbles through a portal between a world that values thinness and one that values roundness. Sometimes falling can wake you up.

Alternate history, self discovery and sweet romance converge in this tale of a young single woman with low self esteem who falls into another world where fat people lead happy, normal, guilt-free lives.
