Some of the best character-first SFF books I’ve read in the last couple years are from the Inspirational market: Patrick Carr’s The Staff and the Sword trilogy, Morgan Bussee’s Ravenwood Saga, and Gillian Bronte Adams’ The Songkeeper Chronicles.
The Staff and the Sword is an adult fantasy set that feels like epic fantasy, but gets you invested in the MC right off and develops him throughout all three books.
The Ravenwood Saga is technically YA, but has broad appeal for adults too. Bussee draws you into a fantasy world, but does so by connecting you to the MC first and following her through the trilogy-spanning story that explores the culture and world Bussee’s created. And it’s available in audiobook too.
The Songkeeper Chronicles is clearly YA, but the message presented is so powerful, it shouldn’t matter what age you are, it’s worth reading. The MC is introduced right away, and I immediately felt for her. Though there were things about this set that I don’t particularly care for (overly thick prose, an annoying secondary character voice, and a couple minor things) it was well worth the time taken to read it, and it spoke to me in a way nothing else has. I cried for several days after finishing book three. I’m going to go through it again, but this time, I’m listening to the audiobooks to avoid some of the issues I had when I read it.
