Nick of Time - L. A. Boruff - Bog

When TIME takes everything Rowena Hembree loves, she calls on friends old and new to take it back.
Raising a teenage daughter by herself and trying to rescue her handler is a lot for one witch, especially one grieving the loss of the love of her life, but Rowena Hembree is determined to undo the wrong from her past that has led to a domino effect of changes to her future.
Nothing is easy and thanks to the TIME agency trying to smooth ripples in the fabric of time, Rowena can't go back and undo the past.
Boy, has she tried. But maybe she can fix it through the present. She calls in old favors and brings together a wayward band of witches to help her hunt down her half-sister and infamous jewel thief, Fiona, who is trying to steal Ro's life to repave her own legacy.
Twists and turns accompany Ro on her journey, and she wouldn't make it without her best familiar, Fred.
Rowena Hembree has been to Hell and back in time. At this point, she can do anything. Including... no, can't tell you that. Spoilers!
