I like my thrillers character-driven & atmospheric, like Courtney Summers in YA and Tana French in adult. Voicy YA mysteries with a classic whodunit feel like TRULY DEVIOUS & PREP SCHOOL CONFIDENTIAL are also up my alley. I'm not a good fit for commercial action/adventure novels.
For YA fantasy, all of the above applies & I am super open to intricate worldbuilding. I love stories with strategists & characters and narratives that fool the reader: STRIKE THE ZITHER & LITTLE THIEVES are recent faves in this vein. Give me mystery too a la YEAR OF THE REAPER!
