Crimson Shepherd [EPUB ebook] 

Sierra Pan is a Capricorn Red. An Accidental Zodiac who is hunted by the Zodiac Enforcement Agency for her very nature. For the past year she’s been keeping a low profile, hiding her aura with a charmed amulet, and staying out of trouble so the Blues don’t capture her. Because she never wants to wear their magic-nulling cuffs again. That changes the day two Blues annoy her enough to warrant teaching them a much-deserved lesson. Saving the kid they were picking on was an unexpected added burden, but now they’re both targets, forcing Sierra to go on the run with the little foundling while trying to avoid the Blues and come up with a plan for their future.
