The Library, the Witch, and the Warder

David Montrose, fired from protecting Washington's witches and grinding through a dead-end clerk job under a vindictive boss, has until Samhain to bond with a new witch or lose his career as a warder for good. When untrained, unexpectedly powerful witch Jane Madison crosses his path, David sees his shot at redemption, if he can juggle her training against his best friend's crisis over stolen artifacts and a brewing conflict with fire salamanders.
