FANTASY
Katabasis
RF KUANG
Speaking of authors we love– RF Kuang marks her return to fantasy with Katabasis, a Dante's Inferno-inspired journey to Hell for a very specific letter of recommendation
You'll find desperate necromancers (Mistress of Bones by Maria Z. Medina), haunting poems (The Executioners Three by Susan Dennard), draconic royalty (Lady Dragon by AM Strickland), and ancient ghosts (Songs for Ghosts by Clara Kumagai) in this month's YA new releases.

Mad Sisters of Esi made a splash on our list of 30 More SFF Titles to Look Forward To in 2025 list last month; books editor Christina Orlando called it "Piranesi through the lens of a creation myth."
EPIC FANTASY
House of Dusk
DEVA FAGAN
We might be a little biased about House of Dusk? We did reveal the cover at Reactor, but an epic fantasy featuring necromancy, assassins, and pyromancy nuns was always going to get our attention.
