(Yes, there’s already a Fave Five dedicated to queer YAs with East Asian female leads, but those are largely by non-Asian/Hapa authors, because it predated the announcements of a few of these books. There’s no overlap in titles, so make sure you check out both posts!)
A Line in the Dark by Malinda Lo (Thriller)
Noteworthy by Riley Redgate (Contemp)
Not Your Sidekick by C.B. Lee (Sci-Fi)
Serpentine and Sacrifice by Cindy Pon (Fantasy)*
*Queer character is secondary in Serpentine, primary in Sacrifice
Seven Tears at High Tide by C.B. Lee (Fantasy)
Bonus: In NA, check out Hold Me by Courtney Milan (Contemp Romance)
