To Save The Few (Crownless Realms #1) by Elvie Grace:
 
Protect your family. Save your friend. Buy your freedom.

For nine years, this has been Seren Clare’s only goal.

But when a deadly mistake thrusts her into the Fae Realms—accused of murdering a Fae Lord—everything changes.

On the run with her sister and best friend, Seren is forced to trust five mysterious Fae soldiers, including the enigmatic Eiran, whose loyalty may come at a cost. As they journey through magical lands and face down deadly creatures, a new danger emerges—one that threatens not only her life, but her heart.

Torn from her loved ones in a brutal ambush, Seren finds herself in Terra Sola, a hidden Fae city cloaked in illusion. Disguised by risky magic and trained by the infuriating yet magnetic warrior Astrophel, Seren begins to question everything she thought she knew—about the Fae, her past, and herself.

But when the chance to save her family resurfaces—at the risk of everything she’s built—Seren doesn’t hesitate. Because freedom has a price. And love might be hers… if she’s willing to fight for it.
