The children in my life just LOVE superheroes. Protecting the universe from man-eating monsters is something that appeals to them. It’s exactly the kind of story they like to create out of their own imaginations while running through the house in a superhero cape.
I point out the superhero fandom because this book was a hit around my house – but it may not be suited to children who are truly terrified by the possibility of death-by-interstellar-monster. The following quote will help determine whether it is suited to your particular child:
Sleepy and full, the creatures retreat. They’ve all had far too much to eat. Feeding time is important, you see – it stops them from eating you and me! We’re safe from the aliens, but just in case, the crew keeps watch from the secret base.
