And the Forest Kingdom Saga is what I'm reading now. I'm now re-reading the fifth book. And it's great. I love it and will forever love it. I also got me the full Deathstalker series as well as some more stuff, but most prominently, the Deathstalker.
Still, FKS is great and I definitely recommend it. I don't think I have a true favorite, but I did really enjoy Blood and Honor as well as the fifth book (BTBM). And no, I don't feel like writing out the full name too many times, it's long.
The FKS is essentially a fantasy fairytale turned inside-out and dragged through a horror story. It's also full of humor. I'm not that huge fan of humor, or mostly my sense of humor is just weird, but I do like the funny stuff in Green's books.
