I reread those just a few weeks ago! I've been recommending them for decades now. (The Intervention & Milieu novels, not so much. I barely got through them).
One piece of advice though: I wasn't sure where my physical books were, so I purchased them on Amazon's Kindle Store. The publisher apparently used a very poor OCR program to scan them in, without no post-scan editing. I made it through the first two alright, but the Non-Born King is almost totally unreadable in the Kindle version--punctuation left out, quote marks missing, many many words misspelled (they may have run a spellchecker on it post scan, and just accepted every correction). It was very frustrating, and I ended up just going to Half-Price Books to buy real copies.
