The Nest by Kenneth Oppel
-Recommended by Mary Severson
Shortly after Steven’s new baby brother, born with multiple birth defects, arrives, Steven starts having dreams about angels—or maybe they’re wasps? At any rate, they tell him, “We’ve come about the baby. We’ve come to help.” Step by step, the wasps work on a perfect new baby, but need Steven’s cooperation for the final replacement. Is he helping or betraying his family? If you liked Coraline, you might like this spooky middle-grade story.
