Blood Ties. Book 4. Fiery Heart

Sydney Sage has to hide too much from her beloved younger sister Zoe, who now works alongside her. Interactions with witches. Personal life. Magical experiments. Zoe is devoted to the mission of the alchemists and their authoritative father. If she learns any of her sister's secrets, she will surely turn away from her. Does Sydney have a chance to show Zoe that life is not limited to blind service?
Meanwhile, Adrian is performing real miracles with spirit magic - perhaps this will help eventually gain protection from Strigoi. But the price for what has been achieved is becoming increasingly terrifying, so he will have to decide whether his amazing abilities are worth the madness that follows?
