Dylan Byron Timeline and Summary

After Dylan's mom dies, his dad takes the family off for a yearlong adventure at sea. Dylan doesn't express any strong feelings about it one way or the other.
On the boat, his job is navigation and math-type stuff. He's a quick learner. He also has practical sailing skills.
Dylan's dad fights with his brother, Ben, almost constantly. Dylan tries to stay out of it.
When his father goes missing, Dylan's absolutely sure it was an accident. Ben thinks Dad killed himself.
A storm hits. Dylan helps Ben sail through the extreme weather and scary waves. He does a good job.
Eventually, the boat crashes into a rock. Dylan and his brothers make a new home on a deserted island that's nearby.
On the island, Dylan is his family's MVP. He gathers food and distills drinking water.
One day, when he's gathering eggs from a bird's nest, Dylan falls off a cliff and breaks his leg. Badly.
Ben rescues Dylan. He tries to put Dylan's leg back in place and clean the wound, but it gets big-time infected.
Dylan tells his brother Ben to let him die. Ben and Gerry aren't having it, though. Ben sets off on a rescue mission, leaving Dylan and Gerry on the island.
Ben finds some rescuers, who in turn rescue Dylan and Gerry. Dylan sails back to civilization and gets surgery on his bad leg.
Dylan's dad returns with a weird story about how he fell off the boat. Dylan, thrilled to see his father, accepts it at face value.
Dylan goes home with his family.
