The Glass Between the Tides (en Inglés) - Hayley Pierce

After the rebellion that shook the kingdom to its core, Sage should be celebrating victory, but the man she loved is gone, and the future she fought for is already slipping away. With Dervla crowned ruler, Trevesiga is starving, unrest is growing, and power rests in the hands of someone Sage no longer trusts.

Haunted by grief and shaken by betrayal, Sage doubts her instincts. But after King Cado's magic spiraled dangerously out of control, survival forces her back into Dervla's orbit-and into the company of Kitto, whose volatility threatens everything they're trying to build.

Sent to the neighbouring kingdom of Aiche to secure a fragile political alliance, and confront a new magical threat endangering both realms, Sage finds an unexpected ally in Trevelyan, a roguish ex-pirate with a painful past of his own. As they traverse perilous lands, he challenges Sage to trust her judgement, and her heart, once more.

With Dervla tightening her grip on the throne, and the fate of two kingdoms hanging in the balance, Sage must confront her grief, reclaim her confidence, and choose whether she will be a pawn in someone else's game . . . or the architect of Trevesiga's future.

An intense, heroine-driven fantasy, The Glass Between the Tides is the second book in the Lightless Alchemist series, and is filled with with political intrigue, high-stakes rebellion, personal demons, and slow-burn romance.
