This was a very short book (little more than 100 pages), and lacked an index which it could have used, but it offers a refreshing take on Greek gods and associated mythology, telling the tale of the Greek pantheon (twelve disciples anyone?!) with an unflinching eye. We learn of Zeus, Hera, Athene, Poseidon, Hades, Demeter, Apollo & Artemis, Hermes, Hæphestus, and Aphrodite, as well as other important characters such as Prometheus, Pandora, Phaeton, Orpheus (yes in the underworld!), Echo & Narcissus, Eros & Psyche, and Arion.
What's striking is how much Christian mythology owes to its Greek forebear. Male god associated with mountains and lightning? Check! male god makes humans out of clay? Check! Those with the power of a god having to walk around in the garden trying to find someone? A god changing into an animal to seduce someone? A huge flood? Check! A man and his wife trying escape burning destruction and because one of them looks back the wife is lost? Check! It's all here: everything the Judaic and Christian pantheons later purloined for their own mythology.
It's entertainingly written and does not shy from the gory bits, so it's no sugary, boring middle-grade series inexplicably set in the USA. I recommend reading this or something like it, if only for the ideas it can deliver for your own writing.
