There's a book? One of my sons said he read the comic (he knew ALL about what was going on in the last 2 episodes which was a good thing since the chained, armless, jawless walkers were a little confusing to me until he explained). Is that the same book?
Well, I more generally meant the comic book which has 103 issues so far, but there are also two novels so far too (Rise of the Governor and The Road to Woodbury).
The last two episodes haven't followed the comics 1-for-1 at all. There has been some basic stuff similar, but there are strong, interesting deviations.
Halloween may be playful fun, but at base it's an irrational notion of ghosts and dead rising from graves, monsters to scare kids, and a practice of terrorism (trick or treat is a threat of harm against extortion of free handouts). Except for the merchants who benefit from sales of candy and costumes, it is a totally empty enterprise perniciously poisoning young minds with fallacious beliefs. This year I decided to introduce a countermeasure: my own magical device to banish fear through "Spin-a-Spell Halloween Twirlers" that create a vortex of protection and are a cute toy besides.

While holidays may have mystical roots, they aren't without value. Christmas is one example. It started from Christian and Pagan roots and the myth of Santa Claus is mystical. Likewise, Halloween is a night about imagination, creativity, and confidence. Children are taught to dress up like whatever they want (something that is generally frowned upon) and knock on people's doors to ask to be rewarded for their costumes.
Btw, what did everyone dress up as? I was Glenn from The Walking Dead.
I'd say there's probably only one shows that rivals it on tv right now, Mad Men.
