Type 1 diabetic, fitness fanatic, dancing queen, Canasta champion; only some of the tags used to describe Colleen Ashby. Daughter, sister to five brothers, wife, and mother of three sons further define Colleen. Add to that, she is a heart transplant recipient who is now visually impaired, and you realize there is much more to learn.

Colleen grew up in the Perth Hills, enjoying a safe and "privileged" childhood, particularly with her brothers always looking out for her. Surrounded by a bunch of boisterous, competitive boys, it's no surprise Colleen developed a passion for sport and fitness, often competing against them. She credits her "can do" attitude to life to the cradle of safety, love, support, and devotion from her family and her inner voice telling her, "You can do it. Don't give up. Do your best. Keep on trying." It instilled in her the confidence that she could do anything. The universe was preparing her for all the challenges she would encounter.

Even with a high level of physical fitness, problems with her heart plagued her and slowed her down. Twelve stents later, the 13th was unlucky; she needed open heart surgery. It was soon obvious her heart was not going to last much longer, and after much discussion, serious consideration, and convincing the "grumpy old witchdoctor", Colleen was placed on the transplant list. This was not the end of the story.

Colleen was given a new heart but due to severe blood loss during the surgery lost 90 percent of her sight. "I'd have been really pissed off if I'd lost it all, but 5 percent? I can cope," she said.

With a bucketful of hope, perseverance, gratitude, and unwavering support of friends and family, Colleen has navigated her new normal, discovering what makes her tick and what her purpose in life is.

Funny, down-to-earth, harrowing, and at times utterly heartbreaking, I Can See Clearly Now is the roller-coaster ride of a woman who continues to defy expectations.
