YA books are YA books when they are being categorized and when arranged on bookstores' shelves for easier spotting. But at the end of the day, anyone can pick them up. According to The Guardian, these stories' themes, although set up for the teenage mind, follow a boundary that's permeable.

While this may not be the sole reason, with Bustle echoing the good in delving into a world that's not about an adult for once as a form of escape from the big, busy and demanding grownup biosphere,  the world of books abound with such stories but we will attempt to pick out five.

1.           "The Graveyard Book" by Neil Gaiman

From the master storyteller and the concocter of worlds one wouldn't imagine to collide, this story follows a kid named Nobody (Bod for short), who decides to live in a graveyard after his parents were murdered. There he makes friends and finds a new family. But all of them are dead too.

As per The Guardian, readers will be taken to a whole new and wonderful world in the first chapters and its humor, riveting stories and curious characters should make the journey worthwhile.

2.          "The Dead Fathers Club" by Matt Haig

This dark, humorous book is something that even those tired of "Hamlet" adaptations should grab. The novel follows a young boy named Phillip whose dead father haunts him one night to assign him a task - to kill his uncle, who his dad says was responsible for his death.

While it is too much for the kid to take in, he did try to be his father's avenger. However, every time he does, his effort is thwarted by all sorts of mishaps.

3.          "The Bad Beginning" by Lemony Snicket

This is the first book in "A Series of Unfortunate Events," which is being made into a web-series by Netflix. This is also the book where the troubles of the young Baudelaire orphans begin - their parents were killed in a fire and they had to live with a distant relative named Count Olaf.

Their new guardian is after the inheritance the eldest if the three, Violet, will get when she turns 18. He's really good at being evil but being bad at showing it. If anything, this book is insanely funny and absurdly fashioned.

4.          "The Walls Around Us" by Nova Ren Suma

This, according to Refinery 29, will take adults straight into the minds of teenage murderers and their past that led to where they are now: in a juvenile facility. As the site described it, the prose in here is "on fire."

5.           "I Capture the Castle" by Dodie Smith

This book is too understated for its real brilliance, as per Refinery 29. It follows the story of a 16-year-old who wants to be a writer. Ironically, her family is impoverished but they live in a castle.
