Mating to a Dragon

Serena Moon-fire, a normal witch with moderate powers has been invited to attend Dragvista, a school for all paranormals. There her powers will grow as she fights the ingrained inter-species racism. She will make friends with Warlocks and leprechauns, werewolves and vampires. And fall undersway of her dragon shifter mate, Drake Silvers. Drake is a dominant, powerful male, perhaps the most powerful there is... and he does not understand the meaning of Freedom of Choice. Will Serena be able to gain ground and freedom from her mate, or will she submit?
Or will she happily fall under her dragons charms and whit, or be made into a pawn for others darker games?
