Dan wakes up a literal world away from home,
on a planet much like Earth. The only difference
is, nearly everyone is gone. Now, with the help of
Phil and the other survivors, he must find a way
home. 

(if you haven't read More Than This, I wholeheartedly recommend you do, as it is amazing and heart wrenching and wonderful and i'll shut up now.)
