Numbers are everything to Grace Lisa Vandenburg. The life of Grace, a Melbourne-based mathematician, is largely governed by her arithmomania, an obsessive-compulsive need to count (three times to ensure accuracy) everything from the poppy seeds on her cake to the bristles on her toothbrush. In a chaotic, sometimes tragic, and constantly changing world, Grace’s preoccupation gives her a sense of order and control. And she does her best to lead a “normal” life, spending time with her mother and sister, her beloved niece Larry… and a manifestation of the late inventor and engineer Nikola Tesla who is Grace’s closest confidante.

Precocious teenager Juliet moves to New Zealand with her family and soon befriends the quiet, brooding Pauline through their shared love of fantasy and literature. This friendship gradually develops into an intense and obsessive bond.
