Spark of the Everflame Series: Book 4, Spice Level Guide

If you’ve fallen for a slow-burn fantasy romance and just finished Heat of the Everflame, you’re probably staring at your Kindle wondering what comes next. The Kindred’s Curse Saga has three books out and one more on the way, but details about the finale are thin on the ground.

Published books: 3 (as of 2025) ·
Author: Penn Cole ·
Series name: The Kindred’s Curse Saga ·
First book release: May 31, 2023 ·

The pattern points to a four-book arc, but the final installment’s date remains missing from every major retailer.

Will there be a 4th Spark of the Everflame book?

Is the series complete?

• The Kindred’s Curse Saga is planned as a 4-book series, confirmed by the author Penn Cole’s official site (author Penn Cole).
• Three books are published as of 2025 — Spark of the Everflame (2023), Glow of the Everflame (2024), and Heat of the Everflame (2025) (publisher Simon & Schuster).

The series has momentum — annual releases, rising readership, and a clear four-book plan. But the missing release date for Burn of the Everflame is the gap that publishers and the author haven’t filled. The consequence: either the series finishes as planned in 2026 or later, or readers face an indefinite wait. For fans of slow-burn romantasy, the choice is clear: catch up on books 1-3 now, or wait until book 4 has a date — and risk missing momentum of the conversation.
