OK... KOONTZ HAS WRITTEN ABOUT GENETICS BEFORE (AND CONTINUES TO DO SO...HENCE, THE CHRISTOPHER SNOW BOOKS.) BUT, I PERSONALLY LIKE THIS BOOK EVEN BETTER THAN WATCHERS (TRANSLATION...IT'S SCARIER!) Eric Leben is a truly frightening villain... he wasn't well glued together before his death and self-imposed resurrection, but he becomes (literally) a monster upon his return. The "shadow fires" of the book's title are psychologically chilling. Leben is definitely one of Koontz's best villains...and that says a lot. He's certainly more interesting than Candy, the vilain of The Bad Place...which nonetheless remains my fav Koontz novel. Anyway, if u are looking to get chills, th is is the book for u. Just realize the book is a bit slow in places. it definitely could've been tighter. BUT the supporting characters in this book are great... especially THE STONE and the sadistic federal agent... Sharp, i believe his name was. so pick this one up... and prepare to be spooked. :)
