We got this book as part of our history curriculum for homeschooling. We read it while also learning about the ancient island of Crete.
The story of the Minotaur has always excited my son, and this story just added fuel to the fire. We both enjoyed learning the background to who the Minotaur was. The writing style was exciting and informative. The final chapter was very helpful in showing what we really know about Crete and what was myth.
The illustrations are a little strange, but intriguing.
I must warn you, this is not for the faint of heart. Some of the stories are violent and gruesome. It is not meant for young children. My 7 year old does not mind this kind of stuff, but I know many kids this age or even older where parts would not sit well. If this is a problem, I would suggest reading it first and figuring out what to leave out (if using it as a read aloud as we did). Not all the stories are problematic in this way. (Although with Greek Myths there is going to be a certain amount of death involved anyway.)
I do not have any real knowledge about Greek Mythology, so I cannot comment on how true to the myths these are or are not. But being as they are myths anyway, they make for a good explanation to Crete history.
