Deriving is a feminist exploration of the creation of life, of family, and of words themselves. Delisle asks: How does past infertility colour the experience of new motherhood? How do historical voices echo in the present? How does language impact our ways of being in the world? These poems embrace the rich material of mothering with unapologetic honesty, confronting the experiences that some would keep hidden. Fear, anger, envy mix with joy and ultimately hope, as Delisle considers the challenges of conceiving and raising children in both familial and global contexts. Deriving is a poignant, lyrical meditation on longing, place, and embodiment.
