Eve Baird - Until the Library recruited her, Baird was the leader of a counter-terrorism squad for NATO. She's a tough-as-nails soldier and a brilliant tactical mind. Now, she must put her military background to use as the Library's Guardian--charged with protecting Flynn and his new recruits as they set out on their harrowing adventures.
Jacob Stone - Born and raised in Oklahoma, Jacob Stone has spent his entire life trying to fit in with the cowboys he works alongside over at the oil pipeline. But the truth is, Stone is a genius when it comes to art, architecture and history. After being targeted for assassination by Dulaque and the Serpent Brotherhood, Stone is recruited by Flynn and Baird to help defeat them and save the Library.
Cassandra Cillian - As far back as Cassandra can remember, she's always been smart. But ever since a life-threatening tumor began metastasizing inside her head, Cassandra has been given the gift of synesthesia--the ability to link all five senses to her memory. For Cassandra, numbers appear as colors, science as musical notes, and when she does math she smells things... mostly breakfast.
Ezekiel Jones - Easily the most morally corrupted of the Library's new recruits, Ezekiel Jones is a world-class thief who looks out for one person and one person alone... Ezekiel Jones. He often comes in handy when the Librarians need to get into an impossibly secure area or out of a tight jam.
Jenkins - Jenkins is the reclusive caretaker of the Library's sleepy little Annex in Portland, Oregon. He's a bit of a hermit by nature and would be more than happy to spend his days holed up in his Magic Lab tinkering away on gadgets.
