Ken Rahmoeller is a chemist living in Michigan who wondered how J.K. Rowling might go about writing another series based on the Harry Potter universe - and then decided to find out for himself. When he's not writing fantasy, he's waiting patiently in front of the mailbox for his summons to teach potions at Hogwarts. If you want to learn more about his writing journey, stop by his website and say hi.
