NOS4A2 by Joe Hill

NOS4A2 is a spine-tingling novel of supernatural suspense from master of horror Joe Hill, the New York Times bestselling author of Heart-Shaped Box and Horns.
Victoria McQueen has a knack for finding things. Riding her bicycle through an old covered bridge, she always emerges where she needs to be. But Vic doesn't tell anyone about her unusual ability—no one would believe her.

Charles Talent Manx has a gift of his own. He takes children for rides in his 1938 Rolls-Royce Wraith, and they slip away to an astonishing playground he calls Christmasland. But the journey through Charlie's twisted imagination transforms his precious passengers, leaving them as terrifying and unstoppable as their benefactor.

And then comes the day when Vic goes looking for trouble . . . and finds Charlie.

Then, one day, Vic goes looking for trouble—and finds Manx. That was a lifetime ago. Now Vic, the only kid to ever escape Manx’s unmitigated evil, is all grown up and desperate to forget. But Charlie Manx never stopped thinking about Victoria McQueen. He’s on the road again and he’s picked up a new passenger: Vic’s own son.

As a life-and-death battle builds—her magic pitted against his—Vic McQueen prepares to destroy Manx once and for all . . .

Disturbing, mesmerizing, and full of twisting thrills, Hill's phantasmagoric, devilishly playful masterpiece is a terrifying high-octane ride.
