The number one bestselling enemies-to-lovers romantasy continues in the second instalment of the 'highly addictive' (The Guardian) City of Fantome series.

The path of destiny burns with love, magic and betrayal...

From a remote hilltop haven, far from the city of Fantome, Seraphine Marchant and her Order of Flames plot to eradicate shade magic with lightfire. But as Sera struggles to control her blooming powers, destiny calls her back to Fantome, and to the assassin who haunts her dreams.

Ransom Hale can't get Sera out of his head. As their rivalry grows and he grapples with the responsibility of leading the Order of Daggers, he feels himself slipping further from who he wants to be. Is he doomed to a life in the shadows? Or can he forge another path?

Meanwhile, rebellion is stirring in the kingdom and a dangerous prince grows in power. Forced to work together by order of the king, Sera and Ransom's conflicted hearts are tested to their limits. And all the while, an ancient prophecy is unfolding that will change the fate of Valterre forever...
