Glass and Frost

Seren Vale has mapped haunted coastlines, contested borders, and a volcanic island that specifically requested not to be charted. She has never failed a commission. She accepts the frost kingdom job because the fee covers two years of her brother’s medical treatment and because unmappable territories are, in her professional experience, only unmappable until someone pays sufficient attention.

Then she arrives at the border and meets her two guides: the fae ambassador assigned to help her — charming, impossibly warm, already lying about something — and the immortal elven lord assigned to let her try — cold, controlled, and keeping a secret that has been kept for two hundred years.

Before Seren can finish the survey and collect her fee, there’s one inn, one room, one bed; a corridor conversation in the dark where he says more than he intended because she asked questions he’d stopped expecting anyone to ask; a compass needle that follows her pen instead of north; a great hall of frozen figures mid-feast where she measures and he quietly names who they were; the sketchbook left open and the fire already burning in her workspace the next morning — no note, no reason — and the woman in the glass column at the heart of the cursed kingdom, and what two centuries of keeping her there cost.

She’s spent her career being told that warmth is a professional liability — that optimism makes you careless, and carelessness gets people killed. He’s spent two centuries building himself into something that functions, that maintains, that does not feel anything it cannot immediately explain, because the last time he felt something fully it went into a glass column and he has been standing at the edge of that room ever since. A frost kingdom waiting to thaw is about to take both of them apart.

Steamy elven romantasy slow burn with a love triangle that actually hurts. The kind of book where the grumpy immortal lord builds a fire in your workspace and is gone before you arrive, and you understand exactly what he meant by it.

WHY THIS WILL SELL

→ Romance > Romantasy sits at 103 sales-to-comp (Hot Cell) with 38 estimated daily sales per top 20 title — the highest-efficiency positioning in the category, where also-bought momentum compounds fastest for new entries

→ “Love triangle” is the highest-indexed trope in Romantasy at 93 Sales vs. Competition Index — stacked here with “one bed” (index 61) and “grumpy/sunshine” (index 41), a combination no current Romantasy top-20 title holds simultaneously

→ “Glass” (index 71, new 2026) and “frost/snow” (index 47, new 2026) are both surging title signals — the title deploys both in two words, giving this package first-mover keyword advantage in two of the market’s fastest-rising search terms

→ Dual-category play: SF&F > Fantasy > Romantic (17.7 sales-to-comp, Hot Mainstream) provides volume discovery alongside the Romantasy Hot Cell — two high-performing placements from a single package

→ Found family (index 51) and forced proximity (index 58) are proven series-readthrough accelerators — readers who attach to a found family ensemble buy the next book for the characters, not just the romance; series readthrough in this category exceeds 60% when the ensemble is established in Book 1

→ “Elf/elven” is up +2 year-over-year and outperforms on a Sales vs. Competition basis against the saturated fae-court market — the immortal elven lord as primary love interest is an underserved combination relative to current reader demand
