Please Don't Tell My Parents I Saved the World Again - Richard Roberts

Magic, mad science, and teenagers are a recipe for trouble. As the only living necromancer, fifteen-year-old Avery Special has too much trouble as it is. Trying to use her dark powers for good, she awakens a cyborg from a coma.

The superintelligent Tonika is grateful and full of plans to help Avery help others, but the more Avery helps, the more trouble she gets in.

Her parents are worried. Her boyfriend and girlfriend are lonely. A robot-possessing ghost is on the loose. Oh, and she stole a crystal ball from a museum. How much helping is too much?

Can she afford to not help when the ultimate evil mad scientist tries to destroy the world?
