Within the Sanctuary of Wings is the conclusion to Marie Brennan's thrilling Lady Trent Memoirs After nearly five decades (and, indeed, the same number of volumes), one might think they were well-acquainted with the Lady Isabella Trent--dragon naturalist, scandalous explorer, and perhaps as infamous for her company and feats of daring as she is famous for her discoveries and additions to the scientific field. And yet--after her initial adventure in the mountains of Vystrana, and her exploits in the depths of war-torn Eriga, to the high seas aboard The Basilisk, and then to the inhospitable deserts of Akhia--the Lady Trent has captivated hearts along with fierce minds. This concluding volume will finally reveal the truths behind her most notorious adventure--scaling the tallest peak in the world, buried behind the territory of Scirland's enemies--and what she discovered there, within the Sanctuary of Wings.
