This is my most favorite Goddess book by P.C. Cast. This story is about how a human woman and a Greek god fall in love. Lena the human woman and the goddess Persephone exchange bodies and souls. Persephone takes on Lena's body and Lena's jobs as a baker. Persephone breaths life back into Lena's bakery and Lena spends time with Hades. Hades is the god of the underworld. This is such a great, and moving, love story. First read Goddess of Spring and then read Goddess of Light. These two books are related to each other. Just keep with the timeline by reading them in this order.
To save her failing bakery, Lina trades souls with Persephone, the Goddess of Spring—and starts falling for hunky Hades.
