A pinch of phoenix
(Book)

Lailu is in hot water. After the events of the Week of Masks, Wren keeps sending insect-like automatons to attack Lailu. However, they're more irritating than dangerous, and Lailu is more worried about the elves, who have been quiet so far. Too quiet. When Lailu heads out of the city on a hunt with Greg, the elves finally strike. They put up a magical shield separating the Velvet Forest from the rest of the city. Now no human can enter...and unfortunately for Lailu and Greg, no human can leave, either. Ryon shows up to save them both, claiming they were caught unintentionally, but Lailu isn't sure she believes him. Tensions between the elves and the scientists are reaching a boiling point, and the question is which side will snap first. And in the middle of it all is Lailu. Trusted by both sides, she's selected to deliver messages and help negotiate a truce between the parties before war becomes inevitable. Easy as pie, right? Not so much. Lailu's new role as mediator may be one recipe that's headed for disaster! --from Amazon.
