There are careers that involve reading submissions for evaluation and to see if that submission can become a published book. But it's tough to get into that field becuase a young student, it is persumed, does not have the experience to read...and then know...what the public wants.
Just get into the publishing business and move in the direction of screening submissions for possible publication.
From what I've seen as a member of the Society of Children's Book Writers and Illustrators, there are careers in reading and evaluating novel submissions as an agent or helping edit novels as an editor for a publishing house. My friends who are freelance editors have a main job and do that on the side.
If you are interested in breaking into the business, there are agents who hire temporary assistants to help them weed through submissions. The college students who do this often do the first read of a submitted novel & then write a report on the merits and drawbacks of the book as a trial and are then compensated later on if the person does a good job.
Most of the major publishing houses hire interns. If you are interested in the publishing business, you might need to live near the headquarters of the publishing houses. My friends who are agents live all over the US and do most of their work online or travel to meet clients.
I only WISH there was a job just reading...I'd be a millionaire! :-)
