My stories aren't about problems. I prefer the term challenges. Even then, my books are not about challenges. They're about characters who have challenges.
In The Ghost Collector, Melinda chooses her challenge rather than having it forced upon her. After getting in disgrace at home, Melinda elects to go to stay with her great-aunt and her three feckless uncles who are planning to open a haunted guesthouse. Melinda thinks poorly of their single ghost, a miserable type named Duncan, so she takes up the challenge to discover more ghosts and transplant them into the guesthouse before the Society for Accuracy in Advertising comes to close them down.
