The Monsters' Monster, by Patrick McDonnell, is a picture book for 3-6 year olds. It features little monsters (Tiny Grouch, Grump and Gloom 'n' Doom) who create a monster. To their dismay, he turns out to be sweet and polite. A cute alternate retelling of Frankenstein, this just came out on September 4.
"The Insomniacs" tells the story of a family who moves twelve time zones away for Mrs. Insomniac's job. They have a difficult time adjusting to their new night schedule, but "Venturing out into the dark, they learn there is a whole world still awake and a beauty in their new and unconventional schedule." I think a lot of people in the Halloween community can relate to this, plus it makes a great bedtime book due to the sleep theme.
Vampirina Ballerina follows a little vampire girl who can't see her reflection in the ballet studio mirror and doesn't particularly look good in pink, yet yearns to be a ballerina.
This cracks me up - That's Not Your Mommy Anymore is a rhyming book you probably wouldn't read to kids under eight. This isn't newly published, but I just had to share it with you anyway.
"One Spooky Night" is also from last year. The pages are filled with intricate paper cuttings. Really artfully done!
Ten Creepy Monsters is a counting down book for kids age 4 and up. Cute rhymes!
Lula's Brew is about a young witch who just wants to be a chef, not cook up potions and cast spells all day.
