Next Door Witch — Mary Stanton

It's not every day you get proof-positive that your maniac seven-year-old brother can shove the very molecules of the world around. Now it's up to fourteen-year-old Natalie to keep her little brother, Denny, from taking everything apart and putting it back together again in a totally different way. At least Natalie has the pearl necklace, the key to controlling Denny's magic. And it's a good thing she's in charge -- because there's nothing worse in life than a bratty wizard!

When Natalie and Denny first showed up to work at Pegasus Farms, they thought Zeuxippe Smith might be a witch. She looked, dressed, and talked like a witch -- and even threatened to turn Denny into a pig! Now, they know -- Zeuxippe's cat and her horse, Old Peg, have magically talked to Denny and begged to be rescued. Normally Natalie tries to stop Denny from using his magic, but it's their only hope to set the animals free from their witchy owner.

Of course, using Denny's magic never means everything will go well...
