Between Their Worlds - Barb Hendee

Wynn Hygeort is stunned when Magiere and Leesil, along with the elven wolf Chap, show up at the Guild of Sagecraft. But Wynn cannot leave with her friends-she still must access the texts within the Guild's archives which may help her divine the locations of the last two Orbs sought by the Ancient Enemy. To complete her task-and protect the Orbs-Wynn must remain sequestered from her friends.

But she's essentially a prisoner. One of the Guild's superiors is just as eager for Wynn to translate the ancient texts, but she knows the others will not permit her to share that knowledge-knowledge Magiere and Leesil desperately need if they're going to stop the Ancient Enemy from unleashing war on the land.
