I'd definitely say so, I definitely enjoyed reading them. The only one that I really didn't particularly enjoy all that much was The Flood (which is a novelization/retelling of the first game with a little bit of extra scenes/characters here and there), but other than that they were all really good for being a bunch of books based off of a video game series. The ones by Eric Nylund especially were really great, aside from a bit of early installment weirdness in the Fall of Reach, which is kind of excuseable since it's the very first book and I don't either Nylund, Microsoft, [i]or[/i] Bungie really knew just how popular Halo was going to prove to be and just how expansive the lore for the series was going to wind up getting. The Cole Protocol is another one of my favorites and right up near the top of the list. If you decide to read them, the best order to read them in would probably be published order, in other words, starting with The Fall of Reach, and then moving on to The Flood, First Strike, and lastly Ghosts of Onyx. The Cole Protocol and Contact Harvest can really be read wherever in there as they can stand pretty well on their own and you don't really need to have done anything besides play the games in order to understand them. Well, actually, you should definitely read The Fall of Reach before you read The Cole Protocol (as the Fall of Reach deals with the origins of the Spartan Program and their training and such), Cole Protocol wouldn't be incomprehensible or anything if you didn't read the Fall of Reach first, but you'll understand the Spartan characters in it and the few little bits that touch on the Spartan Program a whole lot better if you do. And even though I don't like the majority of them, you should give the books published by 343i a try as you never know, while I may hate them and not enjoy them very much, you might. So they're at least worth giving a shot and seeing how you feel about it. The only one that I would [i]actually[/i] recommend as I enjoyed it and felt like it fit in and made sense with the older works is Halo: Evolutions, which is a collection of various short stories ranging from all across the timeline of the Halo series and about lots of different characters, both human and Covenant. So yeah, that one I would definitely recommend reading for sure, and the rest of 343i's stuff I think you should try and see what you think, take whatever negative criticisms I have to say about them with a grain of salt and form your own opinions about them :)
