Emberclaw (Dragon Scales Book 2) by L.R. Lam

Long-banished dragons, revered as gods, return to the mortal realm in the second book in this magical, romantic, epic fantasy series from a Sunday Times bestselling author.

An ancient danger. A broken bond. The fate of two worlds hangs in the balance. 

Arcady and Everen have been separated, parted by the Veil.

Alone in Vatra, Arcady embarks on their greatest con yet: posing as a noble student at the University, determined to prove their grandsire's innocence once and for all.

Imprisoned in Vere Celene, Everen is hated by his kind. When he is released to defend his people, visions of the past and the future haunt him. If he steers the wrong path, he may never create a future where humans and dragons can live in harmony.

Time is running out. Threats rise from Arcady's old life and their new. And between the worlds, an ancient danger is awakening. Together Arcady and Everen can face it - but only if they can find their way back together, and restore the trust that has been broken.
