He is the last flame-shifter prince. She is the hidden frost-born heir. A forced marriage. A dying world. A choice that could destroy magic itself-or rewrite it forever. In a realm where shifters once ruled with elemental power, the royal bloodlines of fire and frost have waged a silent war for centuries. But when Prince Kaelen, heir to the Flameborn, is betrothed to Princess Elira, the last of the Frostbloods, ancient magic begins to stir... and the runes of destiny ignite. What begins as a political union erupts into a forbidden love that defies tradition, prophecy, and time itself. As dangerous secrets unravel and kingdoms fall, Kaelen and Elira must face dragons of the past, trials of fire and ice, and the haunting truth behind the end of all magic. When thrones burn and crowns freeze-what survives is only love.
