Brothers and Sisters
Imagine a future where teens rent their bodies to senior citizens who want to relive the moments of their youth. In Starters by Lissa Price, this is exactly what happens. A genocide spore killed everyone who wasn't vaccinated in time. Left behind are the very young and the very old. Many children are left without parents or caretakers. They must survive in an unfriendly world where they are viewed as unattended minors and are forced to resort to any means possible in order to survive. If a teen agrees to rent out their body to a senior, they are paid a substantial sum of money. It is very enticing to a starving and homeless teenager.
