I just got done reading this. I'm moving to Ironside when it comes over to my library. I haven't seen a summary for it. Wondering if you liked it, if Kaya and Roiben are still in it or if it has different  characters?

Ironside is book three, and they do reappear. Book two is Valiant, which has all new characters who also appear in book three. I suggest reading Valiant before jumping to Ironside, so you know the whole backstory. I liked all three, though Valiant is quite different and more "adult" than Tithe in tone.

Yeah, I just got done looking at the reviews on Amazon. The book itself told me that Ironside was the second book. *shakes head*
