The fourth installment of Raul the Third’s ¡Vamos! series is a love letter to libraries and literacy as well as a celebration of the colorful characters introduced in earlier books. Little Lobo and his dog Bernabé, along with friends Coco Rocho, Kooky Dooky, and new pal La Chida roll through the town library’s annual book festival on Little Lobo’s delivery wagon and La Chida’s skateboard. They take in all the activities celebrating literature, learning, and community. There is something for everyone—romance novels for Bernabé, a tool lending library for La Chida’s skatepark, Lucha Libre comics for Little Lobo, video games for Kooky Dooky, and more! Returning character La Oink Oink teaches festival-goers how to design their own luchadore identity, while Señor Duende offers zine-making for personal origin stories. Raul the Third deftly interweaves Spanish and English words as well as Mexican and Mexican American cultural images and concepts into his distinctive, singular illustrations. A picture book focusing on festive experience over plot buzzes with energy, sprinkling plenty of delights to discover throughout the text and illustrations. (Ages 5-9)
