[1] It is a stand alone prequel to Who Fears Death,[2] it won the 2018 Kurd Laßwitz Preis for Best Foreign Fiction Book[3] and was a finalist for the Arthur C. Clarke Award.

Phoenix is an accelerated biological organism who was created by LifeGen Technologies and lives in Tower 7 in Manhattan with other SpeciMen.

Phoenix is being chased by the Big Eyes and while on the run she develops wings and with the aid of Seven flies to Wulugu, Ghana where she secretly plants the seed.

Phoenix is deemed a terrorist, but she still manages to get inside of the Library of Congress, to learn more about the corporation, herself, her history, her friends and her mother before she heads to Tower 4 along with Saeed and Mmuo.

They successfully free the inmates and find HeLa, who is a SpeciMen who has the DNA that will produce blood that will make the recipient of it immortal.

Phoenix regenerates and "slips" to take a trip to visit her surrogate mother just before the woman dies of cancer.

Saeed survives, which is what he was engineered to do, and leaves the deadland of America and walks to the ruins of West Africa.
