Zip-line is a book for kids that have a scar on their chest from open heart surgery to repair a congenital heart defect (CHD). Used by families, schools and hospitals, Zip-line whimsically explains the answer to the question "How did that line get there?". The story centers around a little girl and her bunny rabbit explaining to the reader how she got the scar on her chest and how she isn't any different than anyone else. It shows her unrestricted in activities and features age appropriate illustrations - no blood, or anything remotely graphic. It aims to set a model for kids with a CHD to be comfortable with themselves, their heart scar, and the surgery that they were too young to remember. Written and Illustrated by a dad whose daughter had a successful 8 hour surgery at 6 months old. Learn more at
