I have not had a chance to read it yet, but I am excited to look through it. My group fought (and narrowly defeated) the Juvenile Horned Dragon at the end of the Beginning Box on Sunday. I am hoping there is more dragon stuff I can throw at them because they had a blast fighting it.
Age of Ashes would be an option if you want dragons. It’s one of the older APs, but it’s a full 1-20 campaign. I haven’t run it yet, but from what I’ve read it needs a bit of work by the GM, particularly around tuning encounters as there are several that are overtuned. Fortunately there are lots of community resources to supplement/augment it.
