Adriana Sinclair is an evolutionary mystery. Her blood type matches nothing in modern medicine. When a failed blood transfusion kills her twin sister, Adriana discovers she's a throwback to an original human that scientists have coined the "Mitochondrial Eve." Adriana is shocked to learn her strange blood type is her family's most protected secret. Working with spotty clues and partial facts, Adriana is determined to find the truth. Still reeling from her sister's death and the subsequent realization of her family's secret, Adriana struggles to put her life back in order and focus on her college studies. She finds comfort in Kalan, the new guy whose striking albino features and friendly manner keep her distracted from the wreck her life has become. Kalan is exactly what she needs right now, even if he does seem a bit too interested in Adriana's mysterious bloodline...

The Brotherhood of the Guardians has existed for thousands of years to serve a single purpose: the protection of Talents, the mortal descendants of the original nine Muses. Twenty-one year-old Daniel Lyoncourt has trained his entire life to join the Guardians. Daniel is prepared to risk his life in order to keep his Talent safe, but when he's assigned to nineteen year-old Anna Saint-James, he discovers that his life isn't the only thing he could lose. Anna has no idea how special she is and knows nothing about her abilities. He must teach her to control her gifts, keep her safe, and hope that he can find a place in her life as something more than just her bodyguard. All power comes at a price. Like all Talents, Anna must one day make a choice: lose all of her powers, or ascend to a higher plane, leaving behind everyone she loves.
