97 The Goblin Emperor

The Goblin Emperor

By

Rated 4.07 out of 5 stars, based on 55,799 reviews.

The Goblin Emperor by Katherine Addison follows Maia, a half-goblin prince raised in isolation who is abruptly elevated to the throne after a fatal airship disaster wipes out the rest of the imperial heirs. Thrust into an elaborate Elven court he barely understands, Maia must navigate rigid protocol, political factions, and subtle technologies in a setting that blends high fantasy with hints of steampunk. As he faces covert schemes, pressure to secure a strategic marriage, and the unresolved mystery behind the so-called accident, his inexperience becomes both a vulnerability and an unexpected strength. The novel focuses less on warfare and more on character, governance, and the ethics of power within a richly detailed secondary world.

Castle Waiting, Vol. 1

By

Rated 4.07 out of 5 stars, based on 7,363 reviews.

Castle Waiting, Vol. 1 by Linda Medley is a low-key fantasy graphic novel set in an abandoned castle that gradually fills with wanderers, outsiders, and the quietly heroic people who maintain it. Opening with “The Brambly Hedge,” a wry reworking of the Sleeping Beauty legend, the book shifts from classic fairy-tale expectations toward slice-of-life storytelling focused on everyday acts of kindness and community. As new residents arrive—a fugitive noblewoman expecting a child, a bearded nun, and an articulate, non-human horse among them—the castle becomes a haven rather than a battleground. Blending humor, adventure, and gentle character drama, this volume offers an adult- and young adult-friendly exploration of what it means to find refuge and belonging in an unlikely place.
