When extreme endurance athlete, Lisa Tamati, was confronted with the hardest challenge of her life, she fought with everything she had. Her beloved mother, Isobel, had suffered a huge aneurysm and stroke and was left with massive brain damage; she was like a baby in a woman’s body. The prognosis was dire. There was very little hope that she would ever have any quality of life again. But Lisa is a fighter and stubborn.

She absolutely refused to accept the words of the medical fraternity and instead decided that she was going to get her mother back or die trying.

This book tells of the horrors, despair, hope, love, and incredible experiences and insights of that journey. RELENTLESS shares the difficulties of going against a medical system that has major problems and limitations. Amongst the darkest times were moments of great laughter and joy. 

RELENTLESS will not only take the reader on a journey from despair to hope and joy, but it also provides information on the treatments used, expert advice and key principles to overcoming obstacles and winning in all of life’s challenges. It will inspire and guide anyone who wants to achieve their goals in life, overcome massive obstacles or limiting beliefs. It’s for those who are facing terrible odds, for those who can’t see light at the end of the tunnel. It’s about courage, self-belief, and mental toughness. And it’s also about vulnerability... it’s REAL, RAW and GENUINE.

RELENTLESS is not just a story about the love and dedication between a mother and a daughter. It is about beating the odds, never giving up hope, doing whatever it takes, and what it means to go ‘all in’. Isobel’s miraculous recovery is a true tale of what can be accomplished when love is the motivating factor and when being relentless is the only option.

"In RELENTLESS, extreme endurance athlete Lisa Tamati, charts her mother Isobel’s remarkable recovery from a brain aneurysm and stroke. Isobel’s life was saved, but from there the medical establishment’s prognosis was bleak as she was left a shell of her former self by massive brain damage.

The book focuses in great detail on the massive challenges Isobel faced to relearn everything from swallowing and eating, to speaking and simply moving her limbs with any self-determination. Her inner resolve, determination and courage shine through as she fights to regain her abilities and quality of life, supported by her children, husband, friends, medical figures and health professionals.

The reader sees Isobel’s immense struggles, tiny gains, and overwhelming triumphs through the eyes of her tenacious and single-minded daughter. Lisa drives her mother’s recovery from the early desperate weeks as Isobel clung on the edge of life and death through the months of painstaking recovery. She boldly dismisses pessimism about her mother’s chances of recovery and researches and employs any technique or technology that could help her mother towards the goal of a full recovery.

The book frequently switches between Isobel’s plight into Lisa’s mind as she tackles the hardest endurance races on the planet – through mountain ranges, deserts and even the full 2250km length of New Zealand. We see the mind-set and fighting spirit that paved the way for Lisa’s sporting success carry through to perhaps the hardest challenge of her life at her mother’s side. Failure is not an option. What also shines through is how Isobel clearly possesses those same fighting qualities. The apple certainly didn’t fall far from the tree!

The book deftly represents the glacial pace of the recovery, which makes the hard- fought gains so satisfying. When Isobel regains another ability you silently cheer her on. Initially it all seemed such an insurmountable mountain to climb but, as the months grind on, she proves the experts wrong time and time again.

When Isobel decides she wants to regain her drivers’ licence she and Lisa return to her doctor’s office to gain a medical certificate. The doctor is astounded by Isobel’s recovery and labels it “one in a million”.

What RELENTLESS teaches us is the one in a million nature of Isobel’s recovery doesn’t need to be so rare. It is available to many more with the latest advances in medicine and technology, tenacity, family support, passion and the willingness to work hard." Matt Calman - Journalist and Author of "The Longest Day" - Standing up to depression and tackling the Coast to Coast.

An amazing book

I couldn't put the book down, what a story, Lisa and her family are amazing, as is their mum, a true inspiration.


A very powerful and positive read.. couldn't put it down once I had started reading...loved the down to earth storytelling, from the heart, learnt so much, the positivity and can do attitude was surely relentless.. I would definitely recommend this very heart wrenching
book...a lot of food for thought...and to remind ourselves to never give up... brilliant.

Jennah-Louise Salkeld
Raw, real and truly inspirational

This story is one that touched not only my heart but my mind. I've always identified as one who was Relentless, however in reading this very raw and real story, Lisa has taught me to open myself up to what determination and being unstoppable truly means; particularly not only in relation to my running, but how I can apply this in all areas of my aspired achievement.

I read all three books of Lisa's in consecutive order and it was an amazing journey to go on with her, and am very grateful to have access to not only this kind of mindset, but the energy of this truly committed soul!

Paul Mulvaney NZ Freelance Journalist & Sports Historian
Faith, hope and love.

Appropriate title of non-fiction of unwavering love of her mother, Isobel and fierce committment from daughter, Lisa Tamati and family.
I have known the proud Tamati family about fifty years and aware that when they focus day by day on the goal they reach it!
Lisa has enjoyed great success in sport.
The book reminds me of a young 2 x Leukaemia survivor, Josh Komen who draws close parallels to Lisa's thought process.
It reinforces like mother,like daughter. To lose this challenge was not an option.


This book is just astounding ! I loved every page . Everyone should read this book . It is a raw inspiring phenomenal story ! Highly recommend .
