A Voyage to the Perisphere is a practical guide for men navigating one of the most significant transitions in their partner's life — perimenopause. Written by a fellow traveller still finding his way through the Perisphere, it combines real science, real stories, and 18 practical tools to help you show up with patience, presence, and the occasional well-timed sense of humour. Whether you're confused, overwhelmed, or just looking for a heads-up, this is the book someone should have handed you the moment your partner first said the word "perimenopause."
