Recurring mothers and disappearing lovers

Conner Mckery had lived his whole life like a normal kid. Well not exactly his whole life. By the time he was eight he had a mother who disappeared more times than he could count and a new girl on the block. Abigail Macosen. She was the coolest person, excluding his father and sister, Conner had ever known. Their adventures as children were always amazing and soon enough they carried the adventures they had into their teen years. But by the time she was fifteen Abigail had a major brain tumor in her head, it covered exactly three fourths of her brain. With little time to spare, Conner takes his best friend on one last adventure, a roadtrip. No actually end point, just one big trip. Watch as Conner, Abigail, Cassandra, Mikey and Hunter make the best of their final days together.
