I really enjoyed the illustrations in this book about a Halloween night.  The illustrations are very dark and creepy, but appropriate for young readers.  Los esqueletos remind me of the figures from the Day of the Dead celebrations.  Despite the creepiness of mummies, skeletons, vampires, witches they all seem happy.  Spanish words are interspered throughout the text.  Words can be figured out through context clues.  Although my monoligual daughter (1st grader) had trouble figuring out what some of the Spanish words meant.  The vocabulary of the book is somewhat high for new readers.  Words like: “beacons”, “clattering prance,” “loon mocks,” and “bloodhounds bay”  might cause them to stumble.  The story is written in four line rhyming stanzas on each page.  All the characters (ghosts, mummies, werewolves, skeletons, etc.) gather together to have a monstrous ball.  They are having a great time, until they hear a knock on the door.  All the monsters hide because the scariest thing they have ever seen is children dressed up for Halloween.  I liked the little twist at the end.  I think kids will get a laugh out of the thought that monsters would be scared of them in their Halloween costumes.
