It's a good and solid read, a little peculiar and a little haunting.
There's a number of books with similar themes. A group of weird kids (often with special powers) get together to save the world. It's a comic book trope, and it's now a teen fiction trope. Think Percy Jackson. Think X-men. Think Hunger Games. Think Spy Kids 1-4. (Okay, the last one is a little too comic relief for this category. But it's the same basic idea.)
Miss Peregrine's is very much like an X-men novel, with added Victorian melancholy and some haunting photographs.

But when his grandfather is killed mysteriously by wild animals, Jacob is drawn to investigate. And when he finds a curious letter from a Miss Peregrine on this same remote island, he manages to convince his dad (an ornithology buff with too much time on his hands) to take a vacation to the island. And then Jacob meets one of the kids from the photos, who hasn't aged a day! That's when the plot really takes off.
Here's a few other books/movies that you might be interested in.

It's not Stephen King horror, but there's a mysterious feeling to it.
I was not surprised at all to discover it's now a series, with 2 books and a third on the way, and a 2016 movie featuring Samuel L. Jackson and Allison Janney and directed by Tim Burton! (Hello, Percy Jackson!)
Anyway, it's well worth reading, if you like this sort of thing. It's definitely suitable for adults. If your kid is into this kind of stuff, I'd say age 12 is the right age, due to lots of violence, some complicated plot issues, and the aforementioned kissing. Commonsense Media says 14.
