The Nest by Kenneth Oppel

Steve knows that there is something wrong with the baby. The baby is sick. Really sick. Deep down sick. They don't know if he is going to make it sick. His parents don't want to talk about it with him, but he sees the trips to the hospital, hears bits and pieces from his parents conversations, and most of all - the haggard look of his parents. Steve's concern starts to grow, especially as he has dreams about the wasps building their nest outside the baby's window. The Queen claims to be able to help, but at what cost?

Oppel has written a wonderful and thoughtful book with terrific illustrations by Jon Klassen. I highly recommend for those who enjoy slightly dark and disturbing tales.
