Fish and Crab are best friends, always there for each other. When it's time for bed, Crab is ready to go to sleep, but Fish is still wide awake, wondering: What is that noise—that ooh, ooh? What if aliens abduct us as we sleep? What if it rains frogs? What if . . . so many things?!

From Marianna Coppo, the critically acclaimed author of Petra, Such a Good Boy, and A Brave Cat, comes an unforgettable picture book about the friendship between two very different aquarium inhabitants. At once relatable and reassuring, Fish and Crab shows the youngest of readers that it is okay to embrace the full spectrum of our feelings—not just at bedtime, but anytime. And that even the biggest worries and "what ifs" are easier to cope with—and move on from—when someone you love and trust is there to listen.
