I don't know if a review is even necessary for this book, I mean we all by now know how epic King is and have heard the hype for this massive book. 
 The one thing I'll say is a lot of people asked me is it scary when I was reading this and I think when you really get down to it, evil clowns and all this story is about the power of friendship. 
 Is it scary? I think that all depends on the reader. What's scary to you? Are Bees scary? Are Spiders scary? Heights? Claustrophobia? Murders? Ghosts? Birds? Clowns? 
 Sure all these things can be scary depending on the person and I think that's how you should look at horror books. Horror fiction is so much more then goosebumps and gore, just like Romance fiction is so much more then smut and love. Themes are an important under current in all books and IT by Stephen King was much more then a cheap jump scare or creepy clown. 
 It is about 7 kids, 7 kids who have witnessed people being murdered and killed all over town, 7 kids who all find in each other as outcast and grow A to love each other. 7 Kids who trust each other enough to confide that they've all witnessed a clown in a silver jump suite and orange pom poms try to lure them away to kill them, 7 kids who are now adults and it's happening all over again. 
 It haunts Derry, It lives in the sewers and comes every 27 years, It feeds of children's fears and limbs. That's all I'd really like to say about the plot, I mean evil monster killing and decapitating a boat load of people is basically all you need to know right? 
 Lets talk about the writing style: 
 It's flawless, faultless, and had me reading in awe and how smooth the whole thing unfolded. 
 There's two timelines, the 7 kids now grown, no memories of what happened 27 years ago but when a phone call awakens them and old scars appear they slowly remember what they did to It all that time ago.A Mixed in to the memories is a flawless transition of those 7 kids setting out to on their first journey, finding each other and unpuzzling the thing that's lurking in Derry. 
 Now as for the scare factors 
 It's there, it has clowns with razor sharp teeth, Werewolves and mummies, it has everything you could ever be scared of: Voices out of the drains, that creepy feeling you get walking into an attic waiting for a hand to grab your ankle, dead kids, bloated bodies. BUT what I really want to point out is even with all these factors this is a story of friendship and the power it has. 
 Friendship between self proclaimed losers, no real talents except their love for each other and determinations to stop It.
