Here's my first draft of the blurb that Anne Mini asked for. Any feedback is more than welcome. It needs to be between 200 and 250 words. This is 233.
Troll Wife applies for the job of tooth fairy, but she doesn't expect to be hired. After all, most faeish respect trolls but don't want to be around them. Becoming a tooth fairy is a happy surprise and at first Troll Wife only sees the benefits. She gets a set of wings that give her the ability to fly and make her look just like everyone else. Best of all, she starts to make friends.
A few days into the job, she discovers that it also comes with a dangerous enemy. Oubliette was said to have killed millions of humans during the Plague Wars hundreds of years ago. The only thing that ended the war is the pact between humans and faeish. Tooth fairies keep that pact, every time they give a child a coin for a tooth. But Oubliette isn't ready to end the war. Anyone not covered by the pact is fair game. Which means any child that has lost a tooth, but hasn't received a coin yet, is in danger.
One of Troll Wife's new friends is a homeless boy with his first loose tooth.
As if Oubliette weren't bad enough, Troll Wife discovers that the tooth fairies are hiding a dark secret of their own. Troll Wife must stop Oubliette before Peter loses his tooth and rescue herself before she's permanently caught in the web of the tooth fairies.
