The Nest: The first thing that struck me was that Steve called the baby "it" in the beginning and didn't use the baby's name until the wasp asked him about it. He didn't seem to be connecting with his baby brother but by the end of the book he saved Theo and risked his own life to do so. I was really interested in the social statement against genetic engineering that evolved as Steve wrestled with the idea of "fixing" his brother's genetics and in the end decided it was wrong. Steve seemed to really be questioning what is "normal" or acceptable both within himself and his brother. I thought there was an interesting connection between Steve's dreams of wasps and the realities of wasps which made it difficult for him to stay grounded in reality. The wasp attack at the end wraps up the story but seems a little hard to believe because Steve survived even with his extreme allergies.
Bone Gap: This book was a little weird to me with the kidnapper being from another world. Like the Nest, I thought the Bone Gap was questioning what is "normal" as Finn is described as strange and we later learn he has a face recognition problem and Petey is described as "ugly". They fall in love but still struggle with whether the other person sees value in them. Of course love prevails and the message seems to be that you want to find someone to love who sees the real you. Love extends beyond romantic love to include brotherly love when Finn is ready to save Roza on his brother's behalf. Finn recognizes that his brother is stuck and that he needs to get Roza back to free himself and get his brother back.
