Ursula Vernon

Danny Dragonbreath and his friend Wendell get an up-close underwater tour of the Sargasso Sea from Danny's sea-serpent cousin, encountering giant squid and mako sharks--and learn about standing up to bullies in the process.

When Suki the salamander--the new foreign exchange student--is being stalked by ninja frogs, Danny, Wendell the iguana, and Suki travel to Great-grandfather Dragonbreath's home in mythical Japan to find a solution for the problem.

From the creator of Dragonbreath comes a tale of witches, minions, and one fantastic castle, just right for fans of Roald Dahl and Tom Angleberger.
When Molly shows up on Castle Hangnail's doorstep to fill the vacancy for a wicked witch, the castle's minions are understandably dubious. After all, she is twelve years old, barely five feet tall, and quite polite. (The minions are used to tall, demanding evil sorceresses with razor-sharp cheekbones.)...

Danny Dragonbreath knows girls are nothing but trouble. And the new foreign exchange student, Suki the Salamander, is the worst: she's reduced his best friend, Wendell, to a blithering, lovesick tadpole. But when a group of ninja frogs attempt to kidnap her, Danny knows he must step in. Danny and Wendell have watched lots of kung fu movies and can totally take on a bunch of ninja frogs. Or, um, so he hopes . . .

"It is Princess Harriet Hamsterbone to the rescue when Heady the hydra's egg is stolen, but her search leads her to a castle accessible only by a rat with a very long tail"--

Danny's mother has disappeared into a fairy ring growing in her backyard vegetable garden, and Danny and his friends, Wendell and Christiana, must go to Faerie to try to save her.

A funny, feminist twist on the Cinderella fairy tale for fans of fractured fairy tales
Princess Harriet Hamsterbone is not the kind of princess who enjoys fancy dresses or extravagant parties. Cliff-diving, fractions, and whacking people with swords are more her thing. So when she's forced to attend a boring ball in honor of a visiting ambassador, Harriet is less than thrilled—until a bewitchingly beautiful stranger arrives. Who is she?...

"When Princess Harriet climbs an enormous beantalk, she finds an even bigger surprise--a giant rabbit is keeping a goose and a girl who is half-harp-half-hamster are prisoner, and it's up to Harriet to save the day"--

Danny Dragonbreath is hoping to see lots of cool bats when he and his best friend, Wendell, visit Danny's cousin, a bat specialist in Mexico. But he isn't expecting to get up close and personal with a giant bat monster, who kidnaps Danny and carries him off to her lair! Now nerdy Wendell will finally get a chance to be a hero . . . but only if he can hunt down the bat monster before she permanently adopts Danny as her bat monster baby.
Ursula...

Never a conventional princess, Harriet becomes an adventurer after learning she is cursed to fall into a deep sleep on her twelfth birthday, but after two years of slaying ogres, cliff-diving, and more with her riding quail, Mumfrey, things go awry at home and she must seek a prince to set things right.
