The youngest American to ever orbit the earth-cancer survivor Hayley Arceneaux-shows us all that when we face our fears with hope and faith, extraordinary things can happen.

A potent reminder to all of us that nothing on earth-or in the heavens, for that matter-can keep us from becoming commanders of our own destiny. -Marlo Thomas, actor, author, and national outreach director for St. Jude Children’s Research Hospital

In this boldly optimistic debut memoir, Hayley Arceneaux details how she overcame seemingly insurmountable odds to grab hold of a life greater than she’d ever imagined. With her signature upbeat messaging, Arceneaux recounts her odyssey, from her cancer diagnosis at age ten and the yearlong treatment that inspired her goal of working with pediatric cancer patients, to living through her father’s terminal cancer diagnosis, to getting her lifelong dream job at St. Jude Children’s Research Hospital as a physician assistant. She was sure she’d finally attained the life she wanted, and then the amazing and unimaginable happened: She was invited to go to space as a St. Jude ambassador.

Throughout the book, Arceneaux encourages readers to fight for the life they want, saying, You have to hold on, because you don’t know what great thing can come and change your life. Take the chance and you will feel, and learn, and grow, and become even more you. Following your dreams can take you to dreams you didn’t know you had.

Arceneaux’s uplifting story is the inspiration we all need today. She offers wisdom and lessons in courage to anyone fighting against the odds. And through it all, she reveals how resilience and faith can help us grab hold of the life we’ve always wanted and live it to the fullest.
