Silver Tongue, Iron Vow. THE ASHEN THRONE CHRONICLES, #3

She can feel a lie before it leaves your mouth. He's been lying his whole career. This summit was designed to kill them both. Lyssa Crane has negotiated seventeen treaties, ended two border conflicts, and talked her way out of situations that should have gotten her killed. Words are her weapons, and she has never met a room she couldn't read. She can already feel that this one is wrong. Aldric Vane accepted the Summit of Iron invitation knowing it was a trap.
Someone wants the Iron Territories destabilized, and the fastest way to do that is to put every significant faction leader in one room and light a match. He just wants to know who struck it. He didn't expect the match to be the most infuriating negotiator he's ever met. Stranded together after the summit's first "accident" eliminates the other delegates, Lyssa and Aldric must survive three days of manufactured diplomatic incidents, Conclave agents, and the increasingly inconvenient realization that the only person either of them can trust is the person they've spent years opposing.
Sharp, witty, and absolutely electric with tension. For fans of The Bridge Kingdom series, Kingdom of the Wicked, and enemies-to-lovers fantasy romance.
