Perfect for you if...

You love slow-burn romance where banter masks genuine connection, and you're drawn to protagonists who soften through vulnerability.
You want fantasy that's whimsical and genuinely weird without taking itself too seriously, with a small-town setting that feels lived-in.
You enjoyed Howl's Moving Castle or The House in the Cerulean Sea and crave that same blend of quirk, heart, and magic.

Maybe not for you if...

You prefer straightforward plots where characters meet and bond immediately rather than ones built on misunderstanding and gradual revelation.
You need your fantasy world-building to be dense and intricate; this prioritises character and charm over elaborate lore.
You're looking for high-stakes drama or dark themes. This is fundamentally a feel-good story about two people learning to appreciate each other.

About this book

Hart is a marshal who patrols the strange and magical wilds of Tanria, a job that leaves him isolated and contemplative. Mercy runs Birdsall & Son Undertakers and has little patience for people like Hart, who always seems to appear when she's at her most frustrated. After a particularly exasperating encounter, Hart writes a letter to "A Friend" seeking connection. To his surprise, he receives an anonymous reply, and the two begin a tentative friendship through correspondence. Hart has no idea that his pen pal is Mercy—the person who frustrates him most. As dangers from Tanria draw closer, Hart and Mercy's written connection deepens into romance. Their relationship faces a critical test when they discover the truth: their anonymous correspondent is their worst nightmare—each other. Set in a world containing magic, demigods, small-town drama, and donuts, this fantasy romance follows two people learning to see past their initial antagonism.
