The Witches of Galdorheim series is about a witch named Katrina (fondly known as Katwitch by her Orca buddy) who feels she can't stay on the little Arctic Island, Galdorheim. Protected by the community of witches, the island is a sanctuary for any witch who's just had enough of real world nonsense.
Kat has a brother. His name is Rune. It's cute, funny, and can spell up a storm (literally), but must constantly be on guard against his father's legacy. Rune is half-vampire and half-witch. Kat thinks he has all the breaks.
Kat, on the other hand, has difficulty learning and executing even the simplest spells. She blames this lack on her human father. She feels if she can't succeed as a witch, she should go find her father's family and see if they'll take her in. As nomadic Sami fishermen, they might be a bit hard to find. She gets help from an unlikely source or two. Mordita, the local crabby old witch, helps Kat and Rune prepare to cross the icy arctic seas to Norway. Why is Rune going? He finds his sister to be very entertaining in her magical failures and he loves her. He wants to help. The siblings get last minute directions from Kat's not-quite-dead father (frozen in a ice cave..don't ask, it's a long story).
NOW, you can get the rest of the setup to Kat's adventures in BAD SPELLING. Then, you can follow Kat, Rune, and her grandfather seek the mysterious MIDNIGHT OIL. At last, Kat is ready to go on her summer abroad to visit Stonehenge for Samhain. She just has to drop off a note to the Trow King in SCOTCH BROOM. As with all Kat's adventures, her little brother just has to come along. This trip that might be a horrid mistake.
That's a heck of a lot of set-up to let you know the COMPLEAT AND TRUE HISTORY OF THE WITCHES OF GALDORHEIM. One volume with all three books, a bonus prequel short story (SPELLSLINGER), and what happens to Rune once Kat has left the island (BLOOD TIES TESTED).
Turning away from Merry, Kat finished the final leg of her pentagram and set the bunny in the center. “Stay right there, Teddy,” she whispered to her little brown rabbit, setting a chunk of carrot in front of him. He made a dash for the edge of the desk. Kat hauled him back. “Cut it out. You’ll smear my chalk lines.” She stroked his soft fur for a moment. “Hope this works.” He twitched his nose twice, closed his eyes, and hunkered down.
Kat checked her spell book one last time, took a deep breath, and completed the spell with a loud “Fullgerður!” and a dramatic sweep of her arms, just missing Merry’s head with her wand.
Merry shrieked and jumped out of her chair. She glared at Kat while wiping green goo off the side of her face. “Your rabbit stinks. Just like your spellcasting!”
Kat’s mouth hung open for a moment; then she clamped it shut when she glanced down at what was left of Teddy sitting in a pool of slime dripping onto the floor. Merry was right about one thing. The goo smelled like pond scum.
