While Headmaster Mordred is trying to impress a new student, the ghost of one of the school's founders besieges the halls seeking his stolen gold.

What are those strange noises coming from the dungeon at DSA? Wiglaf and his stalwart cohorts Angus and Erica decide to investigate and inadvertently free the long-imprisoned ghost of the school founder—Sir Herbert Dungeonstone. Overjoyed to be on the loose again, Sir Herbert wreaks havoc, threatening to spoil the greedy headmaster's plan to turn DSA coed.

When Wiglaf and his pals from Dragon Slayers' Academy meet up with the wizard Zelnoc, all they ask is for a little magic to help them get through the Dark Forest fast. But unfortunately, Zelnoc's spells always end with an "Oops! Sorry about that!" So, yes, the boys are able to travel much faster now...but that's because they have wings, can fly, and have been turned into dragons! And they become the newest students at Dragon Slackers' Academy, a school that teaches knight-slaying! This funny turnabout in which the kids from DSA suddenly see life from a dragon's point of view makes a wonderful addition to this popular series!

Sir Mort engineers a class trip to a home for "olde" knights. But when the lads and lasses arrive, they discover that Sir Lancelot has decided he’s had enough of hacking and whacking and is ready for retirement himself. Find out how Erica (his most fervent admirer), Wiglaf, and the rest of the gang get Lancelot back in action, battling the feared Grizzlegore, the world’s oldest living dragon.

It’s the last day of the school year, so it must be time for Wiglaf and all his friends at Dragon Slayers’ Academy to go home and enjoy the lazy hazy days of a medieval summer. Ummm, not quite. Not when Mordred the gold-hungry headmaster realizes there’s money to be made running a camp. This double-sized summer super special packs in twice the fun for fans of DSA, and there’s a full-color 8-page insert that pulls out and includes a ghost story, jokes, and more. The Horn Book calls DSA "a hilarious and deservedly popular magic-propelled series set in the Middle Ages.

Things couldn't be better for the greedy headmaster of DSA. Lasses are lining up to enroll in his school, and more students means more gold! But when The Medieval Times headline announces that the Bad Luck Dragon is on its way to DSA, Mordred orders his students to hunt for every good luck charm ever invented. But can a bunch of phony 4-leaf clovers help Wiglaf and his friends defeat the dragon Snagglefahng?...or will their luck run out?

Wiglaf ’s latest assignment for the DSA school paper is to write an in-depth article about the headmaster: Who is the real Mordred de Marvelous? Wiglaf, with help from his buddy Angus, decides the best way to learn all about the headmaster is to follow him around school for a day. But when the boys overhear Mordred and his scout, Yorick, whispering about "twins," "kidnapped!" and "gold," they decide to investigate and end up getting much, MUCH more than a newspaper story.
