The main character is Cosmo, with Baker, Seth, Jace, Faith, Ruby, and Cynessa all being very important to the whole story of the book. Cosmo is a timetraveler who has been sent to the year 2021(the year I started writing the book) to stop the world from ending in a way. 2043 is the year when the world ends in the book. Or when Earth ends in the book. The world ends by many many asteroids from space hitting earth, and killing almost everyone. Cosmos job is to stop all of this from happening and change the timeline, or so we thought this was his job.
