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.
