Twindentity is a tool for understanding the relationships between twins, moving away from the cultural view with which we are familiar in myths, legends or literature, which can interfere with twins' interactions with non-twins on a personal and professional level. The book analyses how genetic and environmental factors underpin the construction of twin identity, exemplified through revealing works by contemporary artists.

It is aimed at twins, their families, teachers, researchers, art lovers, and anyone and everyone interested in a greater understanding of relationships between twins, discussing essential topics such as the separation of twins in the classroom, comparisons or criticisms for living parallel lives.
