This adorable graphic novel begins with a little girl playing with her beloved doll, Planeta. When she wishes Planeta good night and falls asleep, the doll wakes up and scurries out of bed to play with the family's spaniel, Elliot, and a mouse, Bradley. This sweet, whimsical story of what toys get up to at night is geared toward early readers, with copious, generally realistic illustrations that nicely evoke the dreamlike scenes. Though much of the story is wordless, the Spanish text is in simple sentences that replicate the cadence of children's speech, with a sprinkling of vocabulary that will improve fluency for both Spanish and non-Spanish speakers. Gentle and bighearted, this graphic novel will leave readers with the parting thought that each creature, big or small, can be its own universe.
