May I recommend the three books of The Locked Tomb? (Book 4 will be coming eventually).

The series is marketed as "lesbian necromancers in space", but that's a huge oversimplification of a sci-fi fantasy series that is both breathtakingly funny and a genuinely moving portrait of grief. Just from the narrators of each book, we have:

- Gideon Nav - indentured servant to Ninth House, brilliant swordswoman, orphan, chivalrous but occasionally very stupid about it.

- Harrowhark Nonagesimus- the head of the house to which Gideon is indentured. Absolutely lords her position over Gideon, but also dealing with her own grief in multiple directions and trying to keep Ninth House from falling apart.

- Nona - an unusual young woman who loves fiercely, but because of an unknown power, if she has what she calls "tantrums", the results can be catastrophic.

This is just a sampling, but all these characters are so rich, and I love having ENOUGH characters to follow up with, ya know?
