From the Goodreads description:
Dexter’s well-organized life is suddenly disrupted when a second, much more visible serial killer appears in Miami. Dex is intrigued, even delighted, by the fact that the other killer appears to have a style reminiscent of his own. Yet he can’t help but feel that the mysterious new arrival is not merely invading his turf, but reaching out to him as well. This new killer seems to be doing more than copying Dexter—he seems to be saying, “Come out and play.” Dexter’s secret life makes for a lonely existence...even a lovable monster can be intrigued by the prospect of finding a friend.Writing
I was actually much more impressed than I had even hoped to be by the author's wit. Dexter is a totally charming and likable guy, you know, except for when he's killing people. I thought the author's voice was so unique and made for such a fun thriller. Dexter's narration is perfect. There's not a thing I would change as far as writing is concerned.
Also quite appealing. It was fast-paced and I didn't see any of the plot twists coming or guess the end of the story before it happened. I think the author found a perfect and frequently hilarious voice for Dexter that really made the book.
No complaints here either. The narrator does a fine job of reading the story and adds well to Dexter's character.
