The Sky is Not Enough: A Heart-Stirring Journey of Dreams, Danger, and Destiny
An Irish woman dares to conquer the skies — and discovers that freedom comes at a cost.
The extraordinary true story of Lady Mary Heath
“A powerful, inspiring story of courage and obsession.”
“Vivid, moving and unforgettable.”
“An extraordinary portrait of one woman who refused to stay grounded.”
In 1928, Sophie Peirce-Evans marries Sir James Heath. With her new titled status as Lady Heath, she embarks on her most daring adventure a solo flight in a biplane from Cape Town to London. Already a trailblazer – a world-record athlete, Britain’s first woman to parachute from a plane and first to earn a commercial pilot’s license – she is determined to prove that women belong in aviation and to showcase the potential of an aviation route from the colonies.
Fiercely independent, Sophie charts her 10,000-mile route using pages from a road atlas, services her own aircraft, and defies every restriction placed on women.
But as she soars over the vast continent memories from a traumatic past her mother murdered, her father imprisoned in an Irish asylum, and a childhood shaped by repression and loss.
Having been stricken with sunstroke, crash-landing in the wilderness and nursed by local women, thwarted at every turn by the authorities and ultimately seeking help from Mussolini, she finally lands in London – heels, furs and all.
Though celebrated, Sophie realises fame cannot free her from her past. She has conquered the skies but not the shadows that follow.

Fascinating historical fiction, celebrating the determination and triumphs of pilot Sophie Peirce-Evans.
Review of advance copy received from Publisher
The Sky is Not Enough by June O’Sullivan publishes with Poolbeg Press January 19th and is described as ‘a heart-stirring journey of dreams, danger, and destiny.’
I had never heard of Lady Mary Heath until I started reading this fascinating account of her life by June O’Sullivan. Mary Heath was born Sophie Pierce-Evans at Knockaderry House, near Newcastlewest, Co. Limerick in 1896. O’Sullivan, originally from Limerick, had grown up not far from Knockaderry House but had been completely unaware of Sophie Pierce-Evans’ story until her twenties. Now, with this sumptuous retelling of her incredible story, blending fact with fiction, O’Sullivan brings alive the challenging and adventurous world of this unknown Irish aviatrix. O’Sullivan describes Pierce-Evans who, through her marriage became Lady Heath, as ‘a rule-breaker, a record-breaker, a pioneer every bit as significant as the names that still trip off out tongues, such as Charles Lindberg and Amelia Earhart…but her star faded too soon’. She also mentions a fact in the notes at the back that is truly amazing. In 1928, Lady Heath sold her plane to Amelia Earhart.
Sophie Pierce-Evans had an extremely difficult beginning, eventually spending time in boarding schools where she found a place to express herself. With an abundance of excess energy and a wild adventurous streak, she turned to aviation after her formal education, becoming an entertainer in the skies. But she had much greater ambition, with dreams to fly solo and further than any aviatrix before her. To accomplish this she needed financial backing but, as a woman, the only way she could access funds was to marry money. Through a friend she was introduced to Sir James Heath, who was intrigued with her nature and sense of ambition, and after coming to an agreement of sorts, their marriage was solidified.
Lady Heath was Britain’s first female commercial pilot but she had to go through very demeaning hoops to prove that women could be as able in the sky as men. Undeterred, she set off, with her husband’s reluctant support, on a solo adventure from Cape Town to London. Along the way she met numerous obstacles but, with persistence, she battled her way through some very precarious situations. At times escaping serious danger, she bounced back, determined to complete this most treacherous challenge.
The world was not quite ready for such a strong-minded and successful aviatrix and Lady Mary Heath, for some unclear reason, drifted out of the minds of folk. While her eventual death was tragic and her earlier years were shocking, O’Sullivan doesn’t dwell too much on her personal tragedies. This novel is a celebration of her successes and her raw grit and ability to strive forward, overcoming massive roadblocks along the way. Lady Mary Heath was a courageous and resilient individual, she was an absolute trailblazer who regularly emerged from her flights wearing her heels and fur, proving that one could fly and be feminine at the same time. She faced, head-on, any chauvinistic behaviour that presented itself and she inspired many women to step out of the traditional roles of the day. Her encouragement was selfless and true. She was an advocate for women across sport and aviation and she herself was known for her athleticism on and off the track.
2028 will be the centenary of Lady Mary Heath’s phenomenal 10,000 mile solo flight. With this enlightening tale, O’Sullivan keeps the adventures of this extraordinary, yet forgotten, Irish woman alive. The Sky is Not Enough is a wonderful tribute to a woman who defied gravity and convention, a woman who wouldn’t be dictated to by a patriarchal society. This is the story of Lady Mary Heath.

More here: Musings on The sky is not enough by June O’Sullivan
I received an ARC of The Sky is Not Enough by June O’Sullivan from BookSirens, and I would like to thank them for this opportunity.
Reading this book has been quite an adventure. First of all, I am genuinely grateful for the chance to discover Lady Heath. We all know Amelia Earhart. She is more than famous. Everyone knows her name. She became the dream and symbol for generations of girls who loved flying and dreamed of becoming pilots. She represents female determination and ambition.
But, as happens so often in history, one name can eclipse many others. Some of those forgotten figures are arguably just as interesting, if not more so, especially because they were the precursors of those who later became legends. The Sky is Not Enough brings forward one of those names: Sophie Catherine Theresa Mary Pierce Evans, later known as Lady Mary Heath. Quite a name, and quite a life.
Lady Heath was very famous in her own time. Born in Limerick, Ireland, her story is fascinating and, most importantly, very well documented. If there is one thing this book deserves real praise for, it is the research behind it. The author clearly did her homework. She manages to reconstruct a complex personal history and to show just how much ambition, determination, and strength it took for Lady Heath to achieve what she did. This, to me, is the book’s greatest achievement: bringing back a historical figure that recent history has largely forgotten and giving readers the chance to truly know her.
I will not go into too many details about Lady Heath herself. I think this is a story worth discovering either through the book or through independent research. However, I do need to talk about the writing choices. I felt that the sections dealing with her childhood and past were significantly stronger than those set in the present timeline. The present-day sections felt strange to me, as if they were trying to balance between a diary-like voice and an omniscient narrator, all while staying in the first person. The result felt unbalanced, and at times I was unsure what the book wanted to be.
This is, of course, subjective, but for my taste those present-day parts were quite choppy.
.....
That said, setting aside the fact that this particular narrative style was not my cup of tea, I truly appreciate books like this. Stories that recover forgotten pieces of history and give voice to people who paved the way for others are one of the great strengths of historical fiction. Reading about topics you know little about, learning unexpected details, and sharing in an author’s passion is one of the joys of reading.

June O'Sullivan's second novel gives us an empathetic and clear-eyed fictional version of an extraordinary real woman: the defiant, determined Sophie Pierce Evans, born in Newcastle West, and one of the world's most intrepid aviators. The book covers the most accomplished slice of Sophie's life following her mission to fly from Africa to England through heat, illness, resistance, injury, bureaucracy and danger. O'Sullivan writes immersively and deftly, bringing this real story to life, and showing how through force of her own will, Sophie faced down a great many obstacles to achieve her goal, and attracted fans, allies, cheerleaders and champions to help her on her way.
This story is written with great sensitivity and intelligence, - it's beautifully and diligently researched, and wonderfully imagined and Sophie Pierce Evans is fully realised as a character - with all her luminosity and all her flaws, so that readers get to see her as she must have been: brilliant, difficult, passionate, stubborn, courageous, vulnerable, determined, complex.
This is no fairy tale. This is real life, lived large in all its elements. She sets goals, she makes mistakes, she takes on the system, she chooses her battles. But no matter what, she keeps going - flying across wild, hot, uncharted terrain to reach her destination. And when she makes it, we understand that this moment doesn't just belong to Sophie (aka 'Lady Mary Heath') but to all women who've been told their dreams are out of reach. This novel is a tribute to ambition, endurance, spirit and courage. It says Do not forget this woman. She was here. She was extraordinary. She mattered

Have you ever heard of Sophie Catherine Theresa Mary Peirce-Evans? How about of Lady Heath? Both names belong to the same person and we should all know her or at least heard her bame, but unfortunately she is one of the many strong and pioneer women lost in history. But thanks to this book that is about to change. Her name should be on par with Amelia Earheart as one of the female pioneers of aviation. Her life is short of spectacular and her feat as being the first female aviator to cross the length of Africa and cross the Mediterranean to arrive back in England.
She had to fight for herself to be awarded a commercial pilot license, but by doing so she was also also she fighting for women equality.
The book is very engaging from beginning to end telling the story of her life since she was a little girl, until she arrives in England after her aviation feat, but don't forget to read the author's note where she gives a full account of what happened to Sophie afterwards, don't want to give any spoilers here.
I'm a fan now of June O'Sullivan and can't wait to read more books from her.

This is a really nicely weighted piece of storytelling by June. It covers an extraordinary life but never feels the need to overstate it.
What stood out most for me was the structure/ Sophie’s life in Ireland is interwoven with her time in the UK and that long, ambitious flight. It all just sits so well together and colours in the main character, in particular, in a very effective way.
The research is clearly extensive, but it’s handled with a light touch. You’re aware of the depth behind it, without ever feeling slowed down by it.
Sophie herself is drawn with nuance. She’s not simplified into a straightforward hero, far from it. Her drive, her past and the contradictions in her character are all there. That enhances the story greatly.
Set in a time when aviation was still uncertain and often dangerous, the book captures the scale of what she attempted.
Written a lovely pace, the book beguiles you all the way through.

Review of advance copy received from Netgalley
Having read and loved the authors previous book The Lighthouse Keeper’s Wife I was really excited to read this one . The blurb sounds excellent and made all the more better that it’s based on a true story . Whilst this book was quite a good read it didn’t quite live up to my expectations. I enjoyed it but I just thought it was lacking something at times . It was a very interesting story but I found it dragged slightly at times . However this certainly won’t put me off reading more books by this author and I look forward to her next one . I found the authors note at the end of this book very interesting and quite sad .

I enjoyed the uniqueness of The Lighthouse Keeper’s Wife and was excited to listen to The Sky is Not Enough. The Irish/English narration was a pleasure. While I didn’t connect much with Lady Mary, I appreciate stories about women forging their own paths, I look forward to the author’s next book!

I'm not a huge fan of fictionalised accounts of a historical figure. However this book did hold my interest. It is the story of a fascinating woman who was an aviator in the 1920s and 1930s. I knew nothing of this woman before or of her enormous achievements.
