Is it OK for the summary of a novel to be nearly the same as someone else's (stephen king's IT)?

I'm writing a novel and I'm a little scared it may be too much like Stephen King's It. My novel is about a kid who gets lost in the woods then a horrible sorcerreer is unleashed. Five people go to kill him. i KNOW it doesnt sound a bit like It, but anyway. Is it ok to have the same outline (roughly) as someone else?
