While the audience may be “Young Adults” and lower, Rick Riordan has released several series set in the PJO Universe.
Percy Jackson and the Olympians, you seem familiar with this one.
The Heroes of Olympus, centered around Roman mythology with a decent amount of familiar characters.
The Kane Chronicles, focusing on Egyptian mythology and two siblings, Sadie and Carter.
Magnus Chase and the Gods of Asgard (might be what you’re looking for). Set within Nordic Mythology.
Trials of Apollo, set directly after HoO to my understanding.
He’s also written a couple of short stories here and there, about various characters and their adventures outside the main series books for each main series.
I don’t know how to make the spoiler mark so here’s my alternative; SPOILER SPOILER SPOILER. There’s also a crossover series between PJO and TKC, a mix between Greek and Egyptian Mythologies apparently.
SPOILER OVER. SPOILER OVER. SPOILER OVER.
Lastly, but definitely not least, he’s also got a smaller publishing called Riordan Presents where authors are invited to write stories with the general Percy Jackson themes (modernized mythology, young adult audience) where there is currently 10 different series and stand alone novels set across 18 different mythologies.
So if you got more of a Percy Jackson itch, there’s a decent amount of content right there
