I have a ritual of constantly rereading my favorite King books on weekends. Firestarter wasn't my top favorite among his works. Interestingly, I saw the original movie first. (Honest advice: Don't even think about watching Peacock's Efron version as it will completely ruin the whole premise for you.)
When I was a little kid, seeing the girl from E.T. eject fire through her eyes was the coolest thing for me to watch! It was even cooler than Carrie's telekinesis power!
A few years later, I read the book and I fell in love with Charlie and her relationship with her devoted father who risks his life to protect his girl! It was an epic, action-packed, and exciting journey!
Nearly 30 years later, I'm repeating my routine and rereading this book, and later I'll rewatch Barrymore's version of the movie. If you have enough time to get lost in this action-packed, supernatural, fast-paced, gripping, and dark journey, I highly recommend you do the same!
