Burning Heart is an adult high-fantasy novel with multiple points of view and complete at 115,000 words
As a greater elemental, Ember could once move mountains and call up storms, turn the earth molten in one breath and quench it with the next. But now, that's all gone. With her nemesis, the Unseelie King, invading Earth again, Ember must regain her connection to the deepest parts of herself or she'll never be able to stop him. - Compared to the dramatic style of the rest of this paragraph, that just seems to fall off a bit. I'm not even going to try to make a suggestion, because frankly, you'll do it better than me anyway!
A millennium earlier, Ember discovered that the Unseelie King killed her soulmate in battle. Absorbed by her grief and rage, Ember lost control of her powers, and in order to save both dimensions from a cataclysm of her own making, she sealed herself in the portal between the worlds. But now, with the portal reopened and her powers absent, Ember must return to the Seelie Court to mourn her loss, learn why she can't reach the elements, and plot her revenge against the Unseelie King. - Hey, great job with this one. So much clearer.
When Ember learns of her soulmate's reincarnation into the human world, all she wants is to leave for Earth. After attempting to go through the portal, Ember finds that she cannot. - I feel like the 'that' is needed in there to tie to the 'that' that starts the next sentence. That what little power she regained is unstable, and because of this, she cannot traverse the dimensions until she reconnects with all four elements.
With the Unseelie King's armies already in Earth and his own greater elemental searching for her soulmate, Ember is running out of time. But with the return of the elements - this just reads like she already has the elements back. Is the quest to recover her elements a big part of the book? If so, maybe make it sound like a future choice? 'However, even if she can retrieve the elements, she'll need to make a choice: find and protect....." comes a choice: find and protect her soulmate or pursue the key to ending the Unseelie King's reign once and for all.
