One bucket list.

One line and once it's crossed, there's no going back...

Luna Truly was living on bottled air and borrowed time.

She had spent most of her life in and out of hospitals.

All she wanted to do was live a typical life-one where she didn't feel like she was a burden.

Everyone treated her like she was a fragile piece of glass, except for one person.

Her best friend, her partner in crime, the boy who she loved for as long as she could remember.

Oliver Hart was the only person who treated her like she wasn't going to break.

He was the only one who really saw the girl behind the medical diagnoses.

He breathed life into her and made her feel alive.

But their time together was quickly coming to an end.

Their lives were going in different directions with Oliver leaving for college in the fall.

It was their last summer before their lives changed forever and neither of them were prepared for what the future might hold.
