Say “¡SI!” to a fresh, funny, Spanish-forward picture book series set in Skeletown—a cheerful, vibrant world filled with Dí​a de los Muertos-inspired characters!

Spend the day with Skully and Skelly as they learn what to say “yes” and “no” to! With the clever use of just two words—síand no—throughout the whole book, a sequence of hilarious gags leads to mischief, chaos, and ultimately friendships soaring to new heights! At first, cautious Skelly reins in Skully's antics, but after they arrive at a friend's birthday party and the games start heating up, Skelly finally comes out of her sugar-skull shell and reveals that there's a hankering for adventure in her after all!

With dynamic, neon art that pops off the pages, a completely unique approach to storytelling, and a wildly appealing (but not scary!) cast of calavera characters from the fantastical world of Skeletown, here's a rambunctious romp that will inspire giggles with Spanish and English readers alike!
