boy whose parents are dark lords?

Please help me remember the name of this book:

Fiction
Plot: a boy has to deal with the fact that his parents are dark lords
When you think it was written or when you read it: read it a couple years ago, probably published within a couple decades
Book's intended audience: Kids (maybe 8 yrs-12 yrs old)

Thanks!

Probably not it, but maybe Dark Lord of Derkholm?

>2 curioussquared: - no, that's not it. Thanks for the suggestion!
