One summer I got a list of the books you should read before starting college.  I went through as many as I could, if I had not read it.  It was a wonderful summer!  I got exposed to many authors and books I might never have read.  There are many such lists.  Here's one.

One of my favorites is The Triffids by the author of The Chrysalids, John Wyndham. It is a post-apocalypse novel that has inspired other novels and films, like 28 Days Later. The hero and narrator happens to be in the hospital recovering from eye surgery with completely bandaged eyes when a catastrophe hits Earth blinding everyone who looks up.

You might want to try James Patterson's Angel Experiment novels. You may also like The Maze Runner series by James Dashner. It definitely has some mystery, but it also a dystopic series and very engaging. Along those lines, I would also recommend checking out the Matched series by Allie Condie and the Divergent series by Veronica Roth. All very good books!

As a mystery fan, you might enjoy the novels of Agatha Christie. She's another exceptionally prolific writer who penned many, many classic mystery stories. 

Stephen King and Dan Brown have also written a good number of page-turning. high-suspense novels. 

If you're looking to get into something a bit more literary, you might look at An American Tragedyby Theodore Dreiser. This is a literary crime tale with quite a bit of quality suspense and literary merit. 

I have reading for over 60 years, so I have a lot of books to recommend. Reading classics is always recommended: Jane Eyre, Wuthering Heights, Pride and Prejudice, Main Street, Babbitt.  Those are lengthy but enjoyable and memorable books.

On the new side, I have enjoyed reading the three hunger game books. They are interesting and worthwhile,  much more so than the Twilight series.  Over the years as they were published, I read all of the Harry Potter books.  I loved them along with the movies.

I agree with most of the books that the #2 post recommends also. Have fun reading this summer.

I always recommend The Catcher in the Rye because it's such a great book for looking at things from a frustarted teenager's point of view. It's a very easy read for an older book.

Because Lowery is a mystery writer, I recommend checking out some classic mystery fiction including Sir Arthur Conan Doyle's original Sherlock Holmes tales and Edgar Allan Poe's short stories -- creepy and fun reading for summer!  They both invented the detective genre as we know it, and it is interesting discovering how much modern writers and filmmakers have borrowed from these two masters.
