Dark Lord: School's Out - Jamie Thomson

After acclimating to the inane customs of the blathering human fools, Dirk Lloyd has managed to make contact with his home in the Darklands. Unfortunately, his powers have betrayed him yet again. His new, and dare he say it, good friend Sooz has been transported to his Iron Tower of Despair, where she awaits what is sure to be a slow and painful end. Little does Dirk know that Sooz has formed her own alliances as the new Dark Mistress of his former kingdom. Dirk must find a way to get Sooz home, especially before his arch-nemesis Lord Hasdruban vanquishes Dirk once and for all. In this equally hilarious and clever sequel, Dirk attempts to regain his evil stranglehold on the Darklands and survive another year in school.
