Pathfinder 2E Which book should I pick up next?

[Libertad]

Sometime this month I'll finish reading the NPC Core, which will be the final of the Remasters for me. I've found the books quite enjoyable reads, but wish to delve more into the world of Golarion via the Lost Omens line. I already read the World Guide, but what book should I pick up afterwards? I'm considering either the Tian Xia World Guide or the Mwangi Expanse, and heard that the Travel Guide is a fluffy in-universe look at various "daily life" activities of Golarion's people. But I am open to hearing other recommendations.

I'm not looking for adventures or adventure paths at the moment.

The Lost Omens guides are all pretty high quality and evocative with great art and inspiration. Is there a region or flavor that interests you more?
If nothing particular hits you, Mwangi Expanse was really awesome.

Don’t forget Impossible Lands too.

I would go for the Mwangi Expanse as it is the other half of the core Inner Sea setting but also brings in a bunch of new stuff compared to the 1e development of the continent.

For me personally Golarion fantasy Africa just is more gripping than Golarion fantasy East Asia.

I'd strongly recommend Rival Academies, its a delightful read.

 

[Simon The Hunter]

Yeah, Mwangi Expanse is a brilliant read. But yeah, all the Lost Omens books are super lore filled and good fun.

 

[Libertad]

Thank you all for your advice! I'm leaning towards Mwangi Expanse now.

Impossible Lands is my personal favourite. I always picked one that was relevant to a campaign I was planning. If you want a good read, then I agree with Voadam...

Mwangi Expanse is the best, in my opinion.
Impossibile Lands and Absalom are also fantastic.
Tian Xia, a bit less.
