"An indispensable book for those of us who love someone with a mental illness." - New York Times bestselling author Pete Earley

A poignant memoir of a caregiver's lifelong struggle to break through the barrier of her sibling's mental illness in search of sisterhood.

Through evocative personal stories, Susan Grundy compassionately explores the devastating consequences of her older sister's severe mental illness. Her diagnosis of schizophrenia at age thirteen eventually leads their disheartened parents to move away to start a new life and to the jarring progression of Susan from a free-spirited little sister into a trapped caregiver.

Susan, candidly and with brave honesty, describes the caregiver push-pull whirlpool where she alternates between fury at her sister's resentful and jealous moods and being flooded with sympathy and guilt - why her and not me? But still, Susan is unable to step away. This memoir, slipping back and forth in chronology, underlines how the past infuses the present. The sisters' journey is woven with resilience and humour and radiates with the potential for well-being and hope despite the collateral damage of a mental illness.

Mad Sisters passionately sounds the alarm about the ongoing lack of resources in the mental health care system. This memoir heartbreakingly sheds light on the burdened family caregiver - the "invisible healthcare partner." Susan spotlights the less common theme of the sibling caregiver and the resulting complexity of skewed family roles.

Inspired by a group of expat artists she met while living next to the jungle in Costa Rica, Susan veered from a long-running career of writing marketing reports to crafting fiction. She has published stories in The Danforth Review and Montréal Writes. Susan then dove into Mad Sisters, a highly personal and challenging project she had been avoiding for decades. A graduate of McGill University, Susan is retired from her 28-year marketing business and is now fully committed to feeding her soul through writing. She divides her time between Montreal and London (UK).

"I finished reading Susan Grundy's memoir with tears in my eyes. Lifelong responsibilities to support her ill sister – mostly as her primary caregiver – have not compromised her unswerving commitment and unabated compassion, despite sometimes feeling frustration, resentment, and sometimes hate. Mental illness can be difficult to forgive when behaviour towards your closest caregivers becomes inexcusably harsh; yet she remains her sister's mainstay through stormy and turbulent times.
Susan's memoir, oscillating between past and present, opens a window into a life marked by the pain and travails evoked by mental illness. Growing up in a volatile household, she became the good girl, though she vacillated between the desire for freedom from responsibilities and the guilt she knew that would bring.
Being a young carer without recognizing it, Susan was subjected to the inevitable impact of mental illness that ravaged her sister's life starting at thirteen. Taking on her sister's physical ailments as if they were her own and bearing the associated stresses, Susan became her ultimate protector, accepting her lot with uncanny generosity.
While Susan does not often lash out at the healthcare system, there is an implicit message that needs to be heard: mental illness is a family affair'; an imperfect, fragmented healthcare system victimizes not only the diagnosed member but their entire entourage." - Ella Amir, C.M., PhD, MBA, Executive Director, AMI-Québec, Allies in Mental Health

"An insightful account of the challenges faced when caring for a sibling with a mental health condition." - Michael Shann,Carers UK
