The Immortalists follows four siblings. As children, they visit a psychic who tells them the exact days of their deaths. That knowledge shapes their entire lives and takes them on diverging paths.
The Rules of Magic follows three magical siblings from the 1960s to 1990s. Their ancestors were cursed so that no one in their family could ever love or else their significant other would face disastrous consequences. But this conflicts with one of the three major rules of magic: Fall in love whenever you can.
