The first trade of Harbinger was really good, I gave it a 4/5 on goodreads, it's nice to read a trade that has a lot of story crammed into it. Plus they put this handy reading order in the back.
Also, fair warning: the Deluxe HCs seem to be coming out at a frequency of less than 1 numbered volume per year. By that I mean we're just now getting to volume 2 for a few titles, but volume 1 has been on stands for more than 12 months. So all depends on how long you can stand to wait to read more. The Deluxe editions are gorgeous, for what it's worth..!
Oh, and be sure to get that Harbinger Wars trade. It's not included in the Harbinger Deluxe, and really is a fun read.
I read Valiant Comics, and you should too!
Hottdamn Imperium is awesome! This whole Toyo/Vine thing is gonna be exciting. Bloodshot was awfully good this week too, I really hope Magic comes out of this unscathed. She seems like a very cool, loyal character...so far.
