Medusa Gorgon's Bad Hair Day by Bethany Walker

Twelve-year-old Meddy Gordon has serious anger issues.

In this hilarious book for middle-grade readers, Meddy rants about family and friendships, using her diary as a way of letting out her anger and keeping her emotions in check.

So far, so normal. You know the kind of thing: frustrations with her self-absorbed sisters; problems with idiotic classmates; disagreements with pompous teachers; and, of course, her troubles dealing with the occasional flock of owls, swarms of snakes, or even the odd many-headed dog.

And then there's the small problem of the snake hair that appears if she doesn't control her anger...

You see, Meddy Gordon is not actually from the twenty-first century. She is, in fact, a human from ancient Greece and she has made a powerful enemy.

Meddy G is MEDUSA and she just happens to have angered Athena, the goddess of war. And what happens when the goddess of war is on the warpath? You get a bad day. A very bad day indeed.
