What Remains of Us (Crownless Realms #2) by Elvie Grace:
 
The Realms left their mark on Seren Clare. Now they must pay the price.
 
After surviving her journey through the Realms, Seren should finally be free.
 
Instead, she’s left fighting an invisible battle with the magic within.
 
As rival Leaders struggle with a tenuous peace following Celestis’s fall, humans are once again at the centre of controversy. With whispers spreading of magic powerful enough to tip the balance between kingdoms, Seren quickly becomes the one thing every ruler wants to claim.
 
Forced into uneasy alliances, manipulated by powerful rulers, and overwhelmed with grief, she toils with anger and betrayal then there’s Astrophel.
 
Whatever exists between them has become tangled in fear, lust, and the uncertainty of what Seren is becoming.
 
Because if the magic inside her cannot be harnessed… Love may be the thing that destroys everything.
