What are the best young adult novels right now on Amazon? Take a look.

Two people meet and fall in love. Then, drama ensues. This is a common theme of many young adult novels.

There may also be dystopian societies, aliens and vampires. But still.

Young adult novels have been the new hit thing in the last few years. Young adult books turned into movies — like “If I Stay,” due out this month, and “The Fault in Our Stars,” released earlier this summer — are indicative of a wider trend in which young adult novels are becoming more mainstream.

But young adults aren't the only ones reading these novels. Older adults are too, especially with the rise of top cultural phenomenons like the Harry Potter series, the Twilight series and, more recently, “The Fault in Our Stars."

In fact, one research study found that 55 percent of young adult novels are bought by adults, although whether or not they should be reading these novels has been a much-debated topic this year.

However, young adult novels don’t seem to be going anywhere anytime soon. So, what are the current best sellers?

Here’s a look at the top nine young adult books being sold on Amazon that don't include sequels or spin-offs:

“If I Stay” by Gayle Forman

“If I Stay” tells the story of Mia Hall, who finds herself caught in between life and death and must make a choice that will define her love life forever more. Starting on Aug. 22, you can catch this film in theaters.

“The Giver” by Lois Lowry

Many will remember “The Giver” from their elementary school reading list. Now the book about a boy living in a colorless world who soon finds vibrancy is heading to the big screen with a film due out this weekend.

“The Fault in Our Stars” by John Green

It wasn’t that long ago when “The Fault in Our Stars” dominated pop culture. Between its soundtrack — with the hit song “Boom Clap” that has snaked its way up the Billboard 100 — and the popular film, which raked in more than $100 million domestically, “TFIOS” — a love story about cancer patients — is surely making an impact still in the country.

The Divergent series by Veronica Roth

Divergent is another series that has found its way into theaters everywhere. Telling the tale of dystopian world and the push to save it from evil, “Divergent” has won the hearts of many Americans. In 2013, "Divergent" reigned supreme in sales with 6.7 copies sold, according to Publishers Weekly.

“The Hunger Games” by Suzanne Collins

Who hasn’t heard of “The Hunger Games?” The book — which has inspired feature films that are setting box office numbers — explains the story of an underdog hero looking to win a competition for the people of her world. The first book in the series sold more than 27 million copies in 2012, according to Publishers Weekly.

“The Maze Runner” by James Dashner

“The Maze Runner” is part “Lord of the Flies” and part “The Hunger Games,” as a young boy has to find a way to survive a dangerous maze. This book is set to come to theaters later this fall.

“Timebound” by Rysa Walker

“Timebound” doesn’t appeal to as many audiences as “TFIOS” might, but it’s got quite the hook. It's about a girl who uses time travel to save a medallion. The book was also the recipient of the Amazon Breakthrough Novel Award.
